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.
Seattle Seahawks rookie guard John Moffitt has also been suspended for four games without pay for violating the NFL's policy on performance-enhancing substances.
The suspensions had been expected. A person familiar with the decision told The Associated Press on Sunday that Davis and Williams were expecting to be penalized after failing multiple drug tests. The person spoke anonymously because of the confidential nature of the league's drug testing policy.
Moffitt will serve his suspension beginning immediately, even though he is currently on injured reserve and out for the season with a right knee injury.
The specifics of why Moffitt was suspended were not released.
Moffitt was Seattle's third-round pick in last April's draft out of Wisconsin and started the first nine games at right guard before suffering a pair of torn knee ligaments in Seattle's Week 10 win over Baltimore. He's one of three starting offensive linemen currently on injured reserve for the Seahawks, along with right tackle James Carpenter and left tackle Russell Okung.
