Dirk Nowitzki not retiring, all but certain to return to Mavs

Dirk Nowitzki is not retiring and almost certainly will spend a 19th season with the Mavericks.

The 7-foot German even says he might have to "unretire" from his national team if uncertainty with European basketball leads to a pre-Olympic tournament ending up in Nowitzki's home country this summer.

"Felt great this year," said Nowitzki, who turns 38 in June and has a player option for the final season of a three-year deal. "Feel like I can still play efficient enough to be there for the team."
