According to ESPN reporter Adam Schefter, the NFL fined Brady $11,139 for appearing to kick at Falcons defensive end Grady Jarrett in the final minutes of their game, and during the same play where Jarrett was controversially flagged for roughing the passer.
Footage of the play shows the Buccaneers quarterback hitting his knee into Jarrett's helmet as the two were on the ground.
It's not the first time Brady has been fined for attempting to kick another player. In 2013, Brady was fined $10,000 for attempting to kick former Baltimore Ravens safety Ed Reed.
