Allen was initially diagnosed with a left quad contusion, and was forced to exit the game late in the first quarter. That injury was suffered when he was kneed in the quad, but the finger injury is of greater concern.
Allen had six points and two rebounds at the time of the injury. He was replaced by veteran Ed Davis.
Allen is coming off the first All-Star Game appearance of his career and averaging 16.3 points and 10.9 rebounds on the season.
