CBS Sports NFL Insider Jason La Canfora reports that Browns quarterback Brian Hoyer, who suffered a nasty injury early in the game against the Bills, suffered a partially torn ACL on the play. The plan is to get a second opinion and then have the knee repaired.
Surgery will end Hoyer's season, but La Canfora reports that no other ligaments were damaged so the injury is not as bad as it could have been.
Hoyer took a shot to the head from Bills rookie linebacker Kiko Alonso but the real damage came to his right knee, which collapsed in painful fashion as Hoyer was unable to get out of bounds or even slide properly.
Hoyer led the Browns to two consecutive victories and appeared to have the starting gig all but sewn up for as long as Cleveland wasn't completely embarrassing itself on offense.
But Thursday's injury opened the door for the return of Weeden, who struggled off the bench but ultimately was able to guide the Browns to victory.
The Browns are fortunate to have their original starter available for backup duty but obviously the injury is a blow to Hoyer, who finally got his shot at leading an NFL team and was making the most of it.
