In the last 14 seconds of Sunday's game, the quarterback led the Tampa Bay Buccaneers on a drive that brought them within two points of the Green Bay Packers.
For Brady, now a seven-time Super Bowl champion, this was a golden opportunity to add yet another game-winning performance to his resume.
After Brady appeared to change the play at the line, the play clock ticked down to zero.
The Packers were able to win 14-12 after recovering an onside kick.
Brady blamed his team's "poor execution" for their delay-of-game penalty.
They also mentioned that on an earlier touchdown throw to Russell Gage Jr., Brady seemed to get away with a late play.
