ORCHARD PARK, N.Y. (AP) - Buffalo rookie quarterback EJ Manuel will miss "a few weeks" with a sprained lateral collateral ligament (LCL) in his right knee.
The injury will not require surgery, Bills coach Doug Marrone said Friday, a day after a 37-24 loss in Cleveland.
Manuel was injured in the third quarter Thursday night, when he was hit by Browns safety Tashaun Gipson at the end of a 14-yard run. Jeff Tuel, another rookie, replaced Manuel but was ineffective, completing 8 of 20 passes for 80 yards.
Marrone said the Bills will look into acquiring another quarterback and did not rule out the possibility of that player starting Buffalo's next game Oct. 13 at Cincinnati.
Also, receiver Stevie Johnson has a strained back muscle that is not expected to keep him out of action, Marrone said. Johnson left Thursday's game in the second quarter and did not return.
Marrone also expressed optimism a number of injured players will be able to return, which include safety Jairus Byrd, cornerbacks Ron Brooks and Stephon Gilmore, kicker Dustin Hopkins and wide receiver Marquise Goodwin.
Bills safety Jim Leonhard was fined $15,750 for unnecessary roughness on a helmet-to-helmet hit on Ravens receiver Deonte Thompson, who suffered a concussion.
