According to the Cleveland Plain Dealer:
Brady Quinn has won the quarterback competition and will start Sunday's game against the Vikings, a league source told The Plain Dealer today.
Browns coach Eric Mangini told the quarterbacks Tuesday night and Quinn took the first-team reps in practice Wednesday afternoon.
Congratulations are in order to TO for correctly breaking this story. It seems Mangini has a leak to deal with. And I guess the Browns have no chance this weekend now that their big secret is out - not that they ever did.
