An MRI taken by Padres left fielder Milton Bradley shows he has a torn ACL, a source with knowledge of the diagnosis told ESPN.com's Jayson Stark, and the volatile outfielder is expected to miss the rest of this season and part of next year, too.

Recovery time from a torn ACL can vary, though 9-to-18 months is typical.

Bradley tore the anterior cruciate ligament in his right knee when he was spun to the ground by his manager Sunday during a blowup with an umpire.

Bradley, who helped spark the wild-card leading Padres during the season's second half, was ejected by Mike Winters. He then hurt his knee during a bizarre scene when manager Bud Black spun him to the ground to keep him from going after the first base umpire in the eighth inning of Sunday's 7-3 loss to Colorado.
