Dirk Nowitzki will likely have MRI on knee

The Mavs are out of the postseason, and Dirk Nowitzki will likely have a precautionary MRI on his knee to "make sure nothing is going to act up next year." Nowitzki had knee surgery that kept him out of action earlier in the season. He's looking to make sure there's no repeat of that in the 2013-2014 season.

He's missed only two games since his season debut in December, a good sign for next season. Nowitzki recently reached the 25,000th point milestone, becoming the 17th player in NBA history to do so.

There's no apparent knee trouble on the horizon for Nowitzki, who isn't expected to be rested in the final week of the season.

Still, a precautionary MRI is a good idea for Nowitzki and the Mavs, who are looking to overhaul their roster at the end of this season. Only  Dirk, Vince Carter, Jared Cunningham and Jae Crowder have guaranteed contracts, though Shawn Marion likely won't opt out of his $9.3 million option.
