Dallas Mavericks forward Dirk Nowitzki’s rehab from arthroscopic knee surgery is not progressing as quickly as he hoped and anticipated.

“When it originally hurt, three to six weeks, in my mind, I’m thinking in two weeks, I’m back,” said Nowitzki, who has returned quickly from several ankle sprains during his 14-year career. “But unfortunately, this is not how it happens. It’s my first knee surgery of my career and unfortunately this stuff takes a little longer than we expected.

“Gotta admit, I’m really already getting tired of rehab these three weeks,” Nowitzki said. “It’s been three weeks. Obviously, that’s a long time for me watching. So I’m really getting tired and bored of it. But at this point, gotta stay patient and do what the doctors and trainers tell me, just keep rehabbing and see how much longer it is.”
