RENTON, Wash. (AP) — Seattle Seahawks cornerback Richard Sherman confirmed he's been fined by the NFL for unnecessary roughness for his hit on Buffalo kicker Dan Carpenter in last Monday's game against the Bills.

Sherman said Thursday that the explanation and wording of the letter from the league makes it nearly impossible for him to appeal. Sherman said the league's justification in the letter was that the hit came after the whistle was blown.

Sherman said he won't appeal the fine.

Sherman was not penalized for unnecessary roughness on the play. He was flagged for being offside, but referee Walt Anderson's explanation after the game said he didn't believe the contact was excessive enough to warrant an unnecessary roughness foul. NFL head of officiating Dean Blandino said that interpretation was incorrect and Sherman should have received a personal foul on the play.
