Derek Fisher strains right knee, doubtful to return

DALLAS -- Mavericks point guard Derek Fisher left Tuesday night’s game against the 76ers after suffering a strained right knee with 6:51 remaining in the first quarter.

He is doubtful to return to the game.

Fisher, who started against the 76ers despite having the flu, was injured after driving to the basket and getting his shot blocked by Philadelphia’s Evan Turner. Fisher fell to the floor and grabbed his right knee. He stayed down for about a minute, appearing to be in significant pain while being evaluated by Mavs athletic trainer Casey Smith.

After Fisher was helped to his feet, he walked off the floor without assistance and immediately headed to the locker room for further evaluation.

The 38-year-old Fisher, a five-time NBA champion with the Los Angeles Lakers, averaged 9.4 points and 3.9 assists in eight starts after signing with the Mavs at the end of November.
