CLEVELAND (AP) — The Browns placed starting offensive guard John Greco on injured reserve.

Greco suffered a sprained medial collateral ligament on the second play of Sunday’s loss in Seattle. The 30-year-old started Cleveland’s first 14 games this season and has started 54 since being acquired by the Browns in 2011.

Browns coach Mike Pettie said Greco will not need surgery. Rookie Cam Erving will likely start the final two games against Kansas City and Pittsburgh in Greco’s spot.

The Browns are also missing starting left guard Joel Bitonio, out with a severely sprained ankle.

Also, the team re-signed rookie wide receiver Darius Jennings to the active roster. Jennings had five catches for 35 yards and returned five kickoffs for 112 yards in two games after being elevated from the practice squad.

Jennings signed with the Browns as an undrafted free agent after playing at Virginia.
