ESPN.com is reporting that Minnesota Vikings quarterback Brett Favre underwent arthroscopic left ankle surgery.
Favre's future has been up in the air since the Vikings lost to New Orleans in the NFC championship game. He had said he would need ankle surgery if he wanted to play in 2010, but there was no word Friday about his playing career.
Messages were left by The Associated Press seeking comment from Bus Cook, Favre's agent. A Vikings spokesman declined comment when asked about the ESPN.com report.
Dr. James Andrews cleaned up scar tissue in Favre's ankle on Friday morning to increase his range of motion, according to ESPN.com.
Favre, who turns 41 in October, said April 30 he had talked to Andrews over the phone about his injured ankle.
