Patriots quarterback Tom Brady limped off the practice field after appearing to hurt his left leg while throwing a pass.
Brady was not hit while throwing a fade to rookie Aaron Dobson that fell incomplete. He was on the ground holding his leg, then began to walk off gingerly but without assistance.
He was met by a member of the team's athletic training staff and walked to the adjacent indoor practice facility. He had not returned to the field after about 30 minutes.
The Patriots were holding a joint practice with the Tampa Bay Buccaneers.
