FOXBORO - Julian Edelman may have agitated his surgically-repaired left foot.

The Patriots wide receiver left the practice field in disgust on Tuesday, throwing his helmet aside before sitting in a cart for an extended checkup with Patriots trainer Jim Whalen.

Edelman left the field at 10:35 a.m., walking off a back hill.

Edelman had surgery on his left foot after suffering a Jones fracture last season. He had a second surgery in April to strengthen the integrity of the area and the implanted screw. He came off the physically-unable-to-perform list and practiced in full pads for the first time on Sunday. 

Edelman's return to the practice field came well before a receiver with a similar injury and two surgeries - the Dallas Cowboys' Dez Bryant - returned from his broken foot.
