Tony Allen returns to action for Grizzlies

Tony Allen returned to the Memphis Grizzlies' rotation Tuesday following a four-game absence due to a knee injury.

Allen came off the bench against the Philadelphia 76ers, his first game action since Dec. 11 against the Charlotte Hornets.

The 33-year-old defensive specialist has had a challenging season so far, shooting below 41 percent from the field and averaging under six points per game coming into Tuesday's game.
