Mavs big man Dirk Nowitzki has been dealing with a sore left ankle for the past few weeks. The Big German has already been ruled out of Dallas' regular season opener, but now it sounds like he might be out of commission for a few more games.

“It’s going to be multiple weeks, I can tell you that,” Mavs head coach Rick Carlisle told Eddie Sefko of SportsDay. “But there’s no soft or hard date. He’s doing better, but has not done any significant court work. We can update you in another 10 days or so.”

Nowitzki had a season-ending procedure on his left ankle back in April. He was suffering from what the team called a left ankle impingement. The surgery was expected to improve his chances of playing this season. Hopefully, he'll be back on the court sooner rather than later.

With Nowitzki's rehab still under way, the Mavs will likely call on some of their other talented bigs to fill the void, including DeAndre Jordan and Dwight Powell.

Nowitzki, now 40 years of age, made 77 appearances with the Mavs during their 2017-18 regular season campaign, racking up averages of 12.0 points on 45.6 percent shooting from the field (40.9 percent from beyond the arc), 5.7 rebounds, and 1.6 assists in 24.7 minutes per outing.

The Mavs will be back in action on Friday night, when they'll welcome the Charlotte Hornets to American Airlines Arena for a fourth preseason game. Tip-off is set for 7:00 p.m. EST.
