Come on people, isn’t there a better use for Twitter other than to talk trash?

Thank goodness for Twitter. Because how else would 49ers TE Vernon Davis and Cardinals LB Darnell Dockett be able to keep their “feud” going during this offseason?

If new Cardinals LB Joey Porter makes headlines with his mouth this coming season — which, according to past history, likely will be the case — coach Ken Whisenhunt certainly can’t be surprised.

The NFL fined Chargers QB Philip Rivers $7,500 for unsportsmanlike conduct in Monday night’s victory over the AFC West rival Raiders, a league source told NFL Network’s Jason La Canfora. Rivers was penalized 15 yards for taunting Raiders DT Gerard Warren in the third quarter of the game.

Cardinals general manager Rod Graves has spoken with the agents for safety Adrian Wilson and linebacker Karlos Dansby in recent days, reports Kent Somers of the Arizona Republic.

The agent for Cardinals franchised linebacker Karlos Dansby is in Arizona meeting with team officials, according to the Arizona Republic.

Eagles QB Donovan McNabb talked earlier in the week about living in Phoenix during the offseason. Cardinals coach Ken Whisenhunt is a neighbor, as are DE Bertrand Berry and S Adrian Wilson. Well, Wilson sure isn’t acting too neighborly today, with two sacks and a forced fumble.

After Sunday’s Arizona-Seattle game, Seahawks quarterback Matt Hasselbeck predicted Cardinals safety Adrian Wilson would be punished for hitting him on a sack.

Wilson, already fined $25,000 this season for knocking out Buffalo quarterback Trent Edwards, professed he “probably” would be fined or suspended.

There’s concern in Buffalo regarding quarterback Trent Edwards’ concussion and whether he will be able to play in the Bills’ next game, Oct. 19, against the San Diego Chargers.

Arizona Cardinals safety Adrian Wilson was fined $25,000 for roughing the passer. Specifically, last week against the Bills he unnecessarily drove the opposing to the ground, violating Rule 12, Section 2, Article 12 (2) of the NFL Official Playing Rules.

Trent Edwards took a vicious hit from Cardinals SS Adrian Wilson and was carted off the sidelines and into the locker room. He appeared to suffer a pretty serious concussion, so don’t expect him back. Fantasy owners who started the Buffalo quarterback this week are looking a goose egg square in the face.
