Brett Favre has a stress fracture in his left ankle that could end the Minnesota quarterback's NFL-record durability streak at 291 consecutive games started. Vikings coach Brad Childress said Monday an MRI on Favre's foot revealed the fracture and an "avulsion" fracture in the calcaneus, which is the heel bone. An avulsion fracture occurs when a fragment of bone is torn away by a tendon or ligament. Favre had arthroscopic surgery on the ankle in May, and he received a series of lubricating injections in the joint at the beginning of the season. The ankle has bothered him at times this fall, but he hurt it in Sunday's 28-24 loss at Green Bay as he was being tackled from behind while throwing his first of three interceptions against the Packers. The 41-year-old Favre was limping around during the game and walking gingerly afterward, and Childress said he was wearing a walking boot around the practice facility on Monday to make him more comfortable. He refused to rule Favre out of Sunday's game at New England, but he also insisted that the streak won't influence the decision on whether to play him against the Patriots (5-1).
