Robert Griffin III Injury Update: Redskins quarterback questionable for Sunday's game

Washington Redskins' quarterback Robert Griffin III is listed as questionable for Sunday's game against the Cleveland Browns, according to the team's Twitter feed. Griffin left in the second half of Washington's game last Sunday against the Baltimore Ravens with a sprained right knee. The league's top-rated passer has been able to participate in team practices all week, though many reporters noticed him favoring one leg on Wednesday and Thursday.

Coach Mike Shanahan told the media that Griffin "keeps on improving every day." The Redskins may wait until game time on Sunday to unveil their starting QB, but Shanahan reportedly said that backup Kirk Cousins will know by Saturday night whether or not he is starting. By not announcing a starter, Washington forces Cleveland to prepare for both quarterbacks.

Friday afternoon, Jay Glazer of Fox Sports reported that Cousins had taken all the first team snaps in practice this week, while Griffin had only done individual drills. However, Glazer re-stated Shanahan's contention that RGIII remains a game-time decision.

The Redskins have won four games in a row, and Griffin has been especially impressive during this stretch. The rookie has posted a QBRating over 100 in each of his last four contests, and has only thrown one interception in that time.
