Washington Redskins quarterback Robert Griffin III was listed a probable on the team's injury report Friday and coach Mike Shanahan indicated that there's a good chance the rookie will be cleared to play Sunday against Philadelphia. Shanahan told reporters Friday that Griffin looked good in practice but had not received medical clearance. He expected that to come Friday night. Griffin suffered a sprained knee two weeks ago in an overtime win over Baltimore and sat our last Sunday's game against Cleveland. He returned to practice this week and took every rep Friday. Rookie Kirk Cousins led the Redskins to a win against the Browns and would start again if Griffin is unable to play. Linebacker London Fletcher (ankle) also was listed as probable for Sunday.
