HATTIESBURG, Miss. — Brett Favre acknowledged he’s ‘‘running out of time’’ to decide whether he’ll play for the Minnesota Vikings this season.

The quarterback told The Associated Press on Wednesday that he’ll give the Vikings an answer on whether he’ll play by the July 30 start of training camp. Favre has been working out with the Oak Grove High School football team three days a week all summer, but added a Sunday workout this week.

‘‘There’s two weeks left and I’m doing everything I can,’’ Favre said. ‘‘I was down here Sunday morning working out. I’m trying to get everything to where I feel 100 percent when I go in. I can’t go in any less. When you’re 39 years old, it’s hard enough. But it’s getting there.’’

The former Packers and Jets quarterback said surgery to repair a biceps tendon in his throwing arm was successful and that he has enough velocity to return to the NFL. He’s just not sure whether that means he’ll be able to compete for an entire season.

‘‘I felt like going to New York last year that I still had it,’’ Favre said. ‘‘I didn’t know my arm was hurt at the time.”
