According to a report from FoxSports.com, Baldwin has been fined $11,025, which is the league minimum for a penalty such as Baldwin's.
Baldwin hauled in a 3-yard touchdown pass from quarterback Russell Wilson with 4:54 left in the third quarter of Super Bowl XLIX. The score gave Seattle a 24-14 lead, but it's what came after the score that drew the league's ire.
After the touchdown, Baldwin dropped the ball, squatted and appeared to simulate defecation. The celebration drew a 15-yard unsportsmanlike penalty from the officials.
Baldwin declined to say whom the celebration was aimed at but acknowledged after the game that it had an intended target.
"That is between me and the guy it was directed at," Baldwin said Sunday night.
