Fred Davis, Trent Williams suspended

WASHINGTON -- The NFL has announced the four-game suspensions for Washington Redskins tight end Fred Davis and left tackle Trent Williams for violating the league's substance abuse policy.

The league said Tuesday that both are suspended without pay and will be eligible to return to Washington's active roster on Jan. 2 -- the day after the final regular season game against the Philadelphia Eagles.

The suspensions had been expected. Sources told ESPN senior NFL analyst Chris Mortensen on Sunday that Davis and Williams were expecting to be penalized after failing multiple drug tests.
