The replay doesn't look good. It looks like it could be an ankle or knee injury, as Dirk came down hard defending a Spurs fast break with 3:18 left in the third quarter.
UPDATE: Dirk was helped off the court. He can't put any weight on his left leg.
UPDATE, PART II: ABC's Michelle Tafoya says Dirk tried to put weight on the leg in the tunnel, but he could not do it. She made it sound like there was pain in the foot, but again, this is just speculation.
UPDATE, PART III: Tafoya confirms that it is a left leg AND ankle injury. Dirk has had X-rays, but the results aren't known yet.
