Mavericks star forward Dirk Nowitzki participated in a full practice Wednesday for the first time since undergoing arthroscopic knee surgery, but he won't be ready to make his season debut until some point after Christmas. "We'll just see how it goes," said Nowitzki, who underwent the operation Oct. 19. "This is the first day stopping, pushing off, moving. We'll see how it reacts. I'm going to do that a couple times, and do some contact for a while. Maybe any time after Christmas, that'll be fun." Nowitzki said he felt "pretty good" after the relatively light practice, which he followed by playing two-on-two with some of the Mavs' low-minutes players. However, he acknowledged that it would take "a while" to get in "halfway game shape" after a two-month layoff.
