Nerlens Noel will undergo surgery on a torn ligament near his left thumb.

Noel will likely be out between four and six weeks.

The Dallas Mavericks hope Noel returns before the trade deadline. Noel rejected a four-year, $72 million offer from Dallas this past offseason and signed for the qualifying offer.

"It's not anything crazy," Noel said. "It's a pretty common injury for a basketball player. I'm just going to get it taken care of. I showed it to the trainers and they said, that it's not right. They said I should probably get some surgery and get it fixed up now.

"I can play basketball with it. A couple guys in here have had it."
