On a first-and-goal near the end of the second quarter, Brady was forced out of the pocket to his left. He ran for 3 yards but slid before he could be tackled. In the process, he raised his right leg and kicked defender Ed Reed in the thigh.

Patriots spokesman Stacey James says he has no information on the fine.
