DALLAS(AP) Dirk Nowitzki of the Dallas Mavericks is out indefinitely with a high ankle sprain and a mildly sprained knee.

It's a blow to the Mavericks' title hopes - and perhaps their chances of making the playoffs. The team announced the diagnosis Monday, the day after the reigning MVP was injured during a game against San Antonio.

The Mavs have lost three straight, continuing a spiral since adding Jason Kidd. They are only 9-8 with the All-Star point guard and hold a half-game lead over Golden State for the No. 7 seed.
