The Spurs and Mavericks are playing in Dallas on national ABC television and just as I flipped it on, Ime Udoka (not Tony Parker) went up for a layup from the right side, Dirk Nowitzki jumped trying to block it, landed strangely and appeared to be in serious pain while lying on the floor, clutching the lower part of his left leg, either the ankle or possibly just above it.

And now he’s being helped off the court into the locker room area by two teammates.

Update: ABC says it’s a ‘leg and ankle’ injury, and an X-Ray has been taken but the results aren’t in yet.

4:26 p.m. ET update from the Mavericks: In today’s game against the San Antonio Spurs, Dirk Nowitzki suffered an injury to his lower left leg at the 3:19 mark in the third period. The injury occurred when Nowitzki got tangled up with the Spurs’ Ime Udoka after blocking his shot. He did not return to the game. Nowitzki will be reevaluated on Monday, March 24.   “I fell awkwardly and my left leg got caught underneath of me,” Nowitzki said. “I am going to get reevaluated in the morning and I hope to have more information then.”
