Browns quarterback Seneca Wallace has a high ankle sprain, said a league source.
It's the same injury that sidelined Jake Delhomme for three full games. When Delhomme relieved Wallace Sunday against Atlanta, he was hobbled throughout the second half and ultimately suffered another sprain to his lower ankle.
Wallace will not be ruled out for Sunday's game in Pittsburgh, however. The source said Wallace will embark on an aggressive rehabilitation program this week in an effort to play.
