Free-agent RB Larry Johnson has agreed to a three-year contract worth up to $12 million with the Redskins, according to a league source.

Johnson began last season as the Chiefs’ starter, but he was released after seven games following a falling out with coach Todd Haley. Johnson finished the season with the Bengals, with whom he backed up starter Cedric Benson and gained 204 yards on 46 attempts.

The Redskins were looking for depth behind starter Clinton Portis, whose 2009 season was cut short by a concussion.

UPDATE: The Redskins later announced that they had signed Johnson, but they didn’t provide terms of the deal.

The Chiefs have agreed to terms on a one-year deal with center Casey Wiegmann and have Monday visits scheduled with guard Ryan Lilja and OT Hank Fraley, according to a league source.

Wiegmann, 36, was a starter for the Broncos last season, and he was selected to the Pro Bowl in 2008.

Lilja was released by the Colts after starting every game for the team in 2009 and 2007. Lilja is drawing interest from other teams as well and could make other visits next week, according to a source.

UPDATE: The Chiefs said later Friday that Wiegmann had signed, but they didn’t release terms of the deal.

Free-agent CB Donald Strickland has agreed to a two-year deal with the Chargers, according to a league source.

Strickland has been in the NFL since 2003 and spent last season with the Jets, with whom he started two of nine games, recording 26 tackles and two sacks. He was a third-round draft pick by the Colts.

The Chargers were looking for cornerback depth after trading Antonio Cromartie to the Jets last week.

UPDATE: The team confirmed the move later Friday.

Free-agent LB Akin Ayodele is scheduled to visit the 49ers on Monday, according to a league source.

Aodele has spent eight seasons in the NFL, including the last two with the Dolphins, who released him last week.

Both the Seahawks and Cardinals are mulling offer sheets for restricted free-agent QB Charlie Whitehurst, according to league sources.

Whitehurst, who has been the Chargers’ No. 3 QB, had impressive visits with Seattle and Arizona and could have an offer sheet within 48 hours.

Both teams need help at the position and, in both cases, Whitehurst, who has yet to throw a regular-season pass in his four-year career, could have the opportunity to start. Regardless, with that level of interest, it seems doubtful the Chargers would keep Whitehurst, resulting in a third-round draft pick as compensation.

Unrestricted free-agent QB Derek Anderson also has visited the Seahawks and Cardinals (he’s currently in Arizona) and could be signed by whichever team doesn’t end up with an offer sheet for Whitehurst.

The Chargers would have seven days to match any offer for Whitehurst.

Veteran OL Rex Hadnot agreed to a three-year, $9 million contract with the Cardinals, according to a league source. The deal could reach $12 million with incentives.

The former Browns lineman had previously visited the Broncos.

Hadnot was a sixth-round draft pick of the Dolphins in 2004 and played four seasons in Miami. He spent the last two seasons in Cleveland.

Disgruntled Redskins CB Carlos Rogers has told the team that he will report for the start of offseason work Monday, according to a team source.

Rogers, the ninth overall draft pick by Washington in 2005, has sought a trade for weeks, and he bristled when a first-round tender was placed on him, hoping to garner an offer sheet.

However, Rogers flew to Washington this week from his Atlanta home to discuss the situation with Redskins coach Mike Shanahan, and the meeting went well, according to sources. If Rogers performs well — he was benched at times in 2009 — he will be considered for a new contract.

Rogers left Redskins Park telling coaches and teammates that he feels better about the situation.

Rogers had voiced his displeasure with the organization and publicly asked for a trade on several occasions this offseason.

Redskins officials are picking up free-agent RB Larry Johnson at the airport this afternoon, according to team sources, and they are very much interested in signing him.

Redskins RB Clinton Portis visited a concussion specialist in Pittsburgh last week and was cleared to begin offseason activities with the team, according to a source, but the team hopes to sign Johnson. The ex-Chiefs and Bengals running back also has scheduled a Monday visit with the Raiders, according to a league source.

Free-agent QB Jake Delhomme has planned a visit with the Saints on Friday and Saturday, according to a team source.

Delhomme, who was released by the Panthers last week and was meeting with the Browns on Thursday, is a Louisiana native, and began his career with the Saints in 1998. He spent five seasons in New Orleans, but he played in just two games before leaving for Carolina.

The Saints are high on young project Chase Daniel, but they haven’t attempted to re-sign veteran No. 2 QB Mark Brunell, according to sources. Delhomme clearly would be behind starter Drew Brees, but has said he’s averse to being a No. 2 QB (he was willing to back up young and unproven Matt Moore had he stayed in Carolina, though).

The Browns’ starting job is wide open. The team acquired Seneca Wallace, who knows Mike Holmgren’s system well, in a trade with the Seahawks on Monday. Attempts to shop Brady Quinn haven’t been fruitful. Browns officials figure a trade of Quinn is unlikely.

Unrestricted free-agent DT Jimmy Kennedy is scheduled to visit the Bills on Thursday, according to a league source.

Kennedy is a valuable contributor to the Vikings, playing behind stars Kevin Williams and Pat Williams (The Williams Wall). Those two players still could face four-game suspensions with the Starcaps case still pending in court.

The Bills are trying to rebuild both their offensive and defensive lines, and they signed OT Cornell Green earlier this week.

With the second overall pick in April’s NFL draft, the Lions have been linked most closely with Oklahoma’s Gerald McCoy and Nebraska’s Ndamukong Suh — widely considered the top two defensive tackles in the draft. But league sources maintain that Oklahoma State’s Russell Okung, a left tackle, remains high on the Lions’ radar because protecting quarterback Matthew Stafford is a top priority.

With Oklahoma and Oklahoma State holding their respective pro days Tuesday and Wednesday, the Lions sent a group of people to McCoy’s workout as well as a contingent that included general manager Martin Mayhew to watch Okung up close.

The Lions, who would eagerly move down in the draft, spent considerable time with Okung at the combine, and it’s well within reason that he could be in play at the No. 2 pick or slightly back should the team trade down.

Free-agent RB Larry Johnson has visits scheduled with the Redskins and Raiders this week, according to a league source.

Johnson, an unrestricted free agent, spent the second half of last season with the Bengals after his much-publicized release by the Chiefs. He played in seven games with the Bengals as a backup to Cedric Benson, rushing for 204 yards on 46 attempts.

The Cardinals and DB Matt Ware have agreed on a multiyear deal, according to a league source.

Ware is a versatile safety who played in 11 games with one start last season, finishing with 24 tackles and one interception. The six-year veteran was an unrestricted free agent who has spent the previous four years in Arizona.

Also, veteran OL Rex Hadnot is in Arizona to visit the Cardinals, according to a league source.

The Browns had worked to retain the lineman, according to a source. Hadnot is a six-year pro who started six games for the Browns in 2009.

There’s still a “very good” chance that veteran WR Derrick Mason will re-sign with the Ravens, according to a source with knowledge of the situation.

The Ravens have signed Donte Stallworth and traded for Anquan Boldin to address their receiver needs this offseason, but they remain very interested in retaining Mason and are in close contact with his representatives, according to league sources.

Mason has been Baltimore’s top receiver since joining the team in 2005 and is a favorite target of young QB Joe Flacco. The Ravens are Mason’s most likely destination at this point, and the team remains confident that it can work to keep him in Baltimore.

Not every free agent visiting teams this week is a household name. In fact, with the first wave of signings over, the bargain shoppers are out and about, looking for a deal.

Here’s a running thread of some of the free agents making the rounds.

• Restricted free-agent LB Marques Murrell is visiting the Broncos on Tuesday, according to a league source. Murrell, who spent the last three years with the Jets, has met with the Patriots as well and is drawing interest from some 3-4 teams.

• Free-agent TE Chris Baker is set to visit the 49ers and Seahawks this week, according to a league source. Baker, who was released last week after one season with the Patriots, spent his first seven seasons with the Jets.

• Panthers unrestricted free-agent DE Tyler Brayton is scheduled to visit the Seahawks Tuesday, according to a league source.

• The 49ers announced Cardinals unrestricted free-agent TE Anthony Becht visited on Tuesday.
