The Baltimore Ravens expect to finalize a contract with free agent offensive tackle Bryant McKinnie on Tuesday, according to a league source.

Lardarius Webb is back on the field for the Ravens, leaving Ed Reed as the lone member of the secondary remaining on the physically-unable-to-perform list.

Oniel Cousins, already replacing starter Jared Gaither at right tackle for the Ravens, was carted off the practice field Wednesday.

One of the biggest question marks surrounding the Baltimore Ravens during training camp has been the depth in the secondary, and Thursday night’s list of inactive players shows just how stretched that unit is.

A quick look around the league and players who have been announced, and reported, as starting the season on the physically-unable-to-perform list.

The trade speculation surrounding Jared Gaither picked up over the weekend, when the Ravens former starting left tackle didn’t participate in the team’s minicamp practices following Friday’s news he had been replaced by second-year pro Michael Oher and moved to the right side.
