Dirk Nowitzki’s surgically-repaired right knee is taking longer than he’d hoped to recover. Nowitzki is already losing patience with the rehab process. Per the Dallas Morning News: “Nowitzki had arthroscopic surgery on Oct. 19. At the time, team doctor T.O. Souryal’s stated prognosis was that Nowitzki would be able to resume basketball activities in six weeks. That would be late November or early December. ‘Gotta admit, I’m already getting tired of rehab,’ Nowitzki said on Fox Sports Southwest’s telecast, during the second quarter of [last night's] game against Minnesota. ‘It’s been three weeks. Obviously, that’s a lot of time for me watching. At this point, gotta stay patient and do what the doctors and trainers tell me. Just keep rehabbing and see how long it is. When I originally heard three-to-six weeks, in my mind I’m thinking ‘in two weeks I’m back.’ But unfortunately, this is not how it happens. My first knee surgery of my career and unfortunately this stuff takes longer than we expected. So I’ve gotta be patient, do the smart thing and keep working.’ Nowitzki said he recently started running in the pool, in addition to riding a stationary bike. He said ‘we’ll probably introduce a little more next week,’ but did not specify what work that might be.”
