Dirk Nowitzki's knee injury isn't believed to be serious, although his owners probably aren't exhaling yet. The All-Star didn't return after being injured early in the second quarter against the Oklahoma City Thunder.
Nowitzki was fouled by Serge Ibaka on a shot attempt and landed awkwardly on his right knee. Though X-rays showed no damage and Mavericks officials said they didn't expect him to miss any significant time, Nowitzki revealed after the game that his knee had bothered him over the past couple of weeks.
