Vikings RE Jared Allen had the torn labrum in his left shoulder surgically repaired on Thursday.
Allen is expected to be ready for training camp. Playing hurt all season, Allen knew about the injury as far back as August but didn't disclose it to reporters until late in the year. Although the surgery will sideline him for most or all pre-training camp activities, Allen usually skips those anyway to train on his own. Allen finished the 2012 season with 45 tackles and 12 sacks. He turns 31 in April.
