NFL notes: Johnson's TD act costs him $10,000

Buffalo Bills receiver Stevie Johnson has been fined $10,000 by the NFL for mimicking shooting himself in the thigh during a touchdown celebration last weekend that mocked New York Jets receiver Plaxico Burress.

A person familiar with the league's disciplinary action informed The Associated Press of the fine on Wednesday. The person spoke on the condition of anonymity because the league has not made an announcement.

Johnson, a former Kentucky star, declined to confirm whether he had been punished except to say he had an overnight courier envelope from the NFL waiting for him at his locker when he arrived for practice. Johnson left the envelope unopened because he expected to find inside formal notification of his fine.

On his Twitter account, Johnson made light of the envelope by referring to it as "the Random FedEx Package in My Locker" and posting a picture of it.

"I'm not really worried about a fine right now," Johnson said. "It's part of the game. People get fined. But we've still got a football game on Sunday."

Johnson added he regrets making fun of Burress and has apologized to the Jets player. He also said he plans to stop performing touchdown celebrations.
