Milwaukee center Jericho Sims, who appeared in 14 games since being acquired at the trade deadline, underwent surgery on Monday morning to repair a torn ligament in his right thumb, the Bucks announced,

The Bucks said Sims is expected to miss four weeks, meaning he probably won't return until postseason play begins. The playoffs start April 19, with the play-in rounds taking place April 15-18. Milwaukee (38-29) is currently fourth in the Eastern Conference, and the play-in rounds are for teams that finish seventh through 10th.

The Milwaukee Bucks may have been dealt another blow to their front court as center Jericho Sims may need surgery on his right thumb. Sims sprained it against Indiana on March 15 sometime in the first half.
