This is by no means laughing matter. The Washington Redskins are attempting to make a playoff push as the season is closing out and they face a tough and red hit Cleveland Brown team on Sunday. 

Rookie quarterback RGIII will not start Sunday's game against the Browns after failing to overcome a knee sprain

"The decision was not my own..." Griffin tweeted on Saturday. "But I will be there for my team!!! In every way I possibly can."

The Redskins are expected to start rookie quarterback Kirk Cousins in his place. It will be his first career start in the NFL. 

However, you can't count out Cousin who stepped up big last week with a game-winning touchdown late against the Baltimore Ravens. Of course, you would prefer for RGIII to be on the field, especially at this point of the season and the games' significance. 

Washington (7-6) are second in the NFC East, a game behind the New York Giants (8-5) in the division and the Chicago Bears (8-5) and Seattle Seahawks (8-5) in the wild card race with three games to play.

The Browns have been rolling winning three consecutive games after getting 2012 off slowly.
