Dirk Nowitzki has undergone minor surgery on his left ankle.
Nowitzki will miss the remainder of the season.
Nowitzki played in 77 of the Mavericks' first 78 games of the season.
Nowitzki was questionable for last Sunday's game with a left ankle impingement, which is a problem related to bone spurs, something that Nowitzki has had periodic problems with throughout his career in both ankles.
