Canadian Anthony Bennett, a projected top-10 pick in June’s NBA draft, underwent shoulder surgery Wednesday, and could be sidelined for as long as four months.

The 20-year-old power forward from Brampton, Ont., had surgery to repair a torn rotator cuff in his left shoulder, and is expected to miss both pre-draft workouts and the Summer League.

After his surgery, Bennett tweeted: “Everything is good, they said it went well , appreciate everyone that sent their wishes & prayers.”

Most mock drafts have the 6-foot-8 Bennett going either fourth or fifth in the June 27 draft at the Barclays Center, home of the Brooklyn Nets.

Bennett played one season at UNLV, earning Mountain West freshman of the year honours. He started in 32 of 35 games, and led the team in scoring with 16.1 points a game. He also led the team, and was fifth in the conference, in rebounds averaging 8.1.
