Eddie Sefko of the Fort Worth Star-Telegram reports:

Dirk Nowitzki sprains ankle, plays anyway

Humming along with a double-digit lead and the look of a team with payback on its mind, the Dallas Mavericks got a scare just before halftime Wednesday night.

Dirk Nowitzki went down in a crumble under the defensive basket with a sprained right ankle.

But rather than a difficult circumstance that could have ended up being an excuse for a letdown, the Mavericks — and Nowitzki — turned it into an opportunity, and a 106-91 thrashing of the Memphis Grizzlies.

At the start of the second half, Nowitzki was back on the court, clearly favoring his right leg, but determined to be there for his team.

In the Mavericks’ huddle, coach Rick Carlisle leaned in to his assistants and said: “He’s one tough dude.”
