Boston Celtics center Robert Williams underwent surgery for a torn meniscus on Wednesday morning. Following surgery, the expectation is that Williams will return to the lineup in 4-6 weeks.

Williams was injured at some point in the Celtics victory over the Minnesota Timberwolves on Sunday. Imaging showed the fourth-year center tore his meniscus in his left knee.

There is optimism Williams could return on the shorter end of his timeline. Four weeks would have Williams back towards the end of the first round or beginning of the second round of the playoffs.
