Redskins left tackle Trent Williams and tight end Fred Davis have been suspended four games for violating the league's substance abuse policy, Jim Trotter of Sports Illustrated reports. Last month, Davis and Williams were identified by ESPN's Adam Schefter as two of 11 players that tested positive after the lifting of the lockout. Jason Cole of Yahoo! Sports initially reported the eleven positive drug tests. Trotter adds that the suspensions will begin next week, meaning this afternoon's game against the New York Jets will be the final game each player will play in 2011. Source: Mac's Football Blog
