Inside linebacker Keenan Robinson underwent an MRI exam Thursday evening after leaving the Redskins’ afternoon practice with an injury. Results were not immediately available. Trainers and a team doctor evaluated his left shoulder area on the field. Robinson tore his right pectoral muscle last Thanksgiving Day.

Defensive end Adam Carriker is expected to miss four to five months after right quadriceps tendon surgery Thursday, coach Mike Shanahan said. That probably will cost him the season. For now, he’s on the active/physically-unable-to-perform list with guard/tackle Maurice Hurt (right knee).


Cornerback Josh Wilson (left labrum/pectoral) was cleared to practice midday Thursday after he demonstrated his strength in the weight room, Shanahan said.

The Redskins waived second-year free safety Jordan Bernstine because he still was not recovered from the severe right knee ligaments injury he suffered last season in Week 1, Shanahan said. Washington signed free agent safety Jose Gumbs and cornerback Ryan Mouton to replace Bernstine and waived safety Devin Holland on the roster.

Outside linebacker Brian Orakpo (left pectoral) and tight end Fred Davis (left Achilles’ tendon) will fully participate in practices, Shanahan said.

Strong safety Brandon Meriweather (ACL, right knee) partially participated in team drills. It’s precautionary as he works back into practice for the first time since suffering the injury last Nov. 18.
