Moffitt was already on injured reserve and wouldn’t have played in the final four games of the season anyway, so the suspension effectively just means he’ll be fined four weeks’ pay.
There’s no word on which performance-enhancing substance Moffitt tested positive for. He and his agent haven’t commented, and the league and the team can’t say anything because everything having to do with drug tests is confidential.
Moffitt was an All-American at Wisconsin last year, and the Seahawks chose him in the third round of this year’s draft, with the 75th overall pick. He started the first nine games of the season before suffering a knee injury.
