Steelers' Antonio Brown fined by NFL for goalpost celebration

Pittsburgh Steelers receiver Antonio Brown has been fined $11,576 for Sunday's goalpost celebration, a source confirmed to ESPN's Chris Mortensen.

"I got a little fine for it," Brown told the Pittsburgh-Tribune Review, which was first to report the fine, on Wednesday. "They [the NFL] didn't like it too much."

Brown received an unsportsmanlike penalty for "using the goalpost as a prop" late in the Steelers' 45-10 win over the Colts on Sunday.

After crossing the goal line, Brown jogged toward the goalpost and jumped onto the post's padding with his arms and legs outstretched, slamming his midsection into the pad. Brown had the football in his left hand and had trouble holding onto the post, so he fell and landed on his back.

"I was full of excitement," Brown said on NBC after the game. "I tried to stick it at the goalpost, and it just didn't work out."

Brown's celebration came after a 71-yard punt return -- his third score of the night -- with 4:01 left. Teammates mobbed him after the play.

Steelers coach Mike Tomlin was less enthused after the game when told of what drew the penalty.

"I didn't see it," Tomlin said. "But I'm sure we'll rehash it and rehash it a thousand times in the next six days and suck all the life out of it."
