An already disappointing season for the Philadelphia 76ers suffered another blow on Saturday when the team announced that rookie guard Jared McCain – one of its few bright spots – will undergo surgery for a torn lateral meniscus and will be out indefinitely.

The 20-year-old McCain was arguably the best rookie in this year’s class, averaging 15.3 points per game – tops among rookies – while shooting 46% from the field and 38.3% from 3-point range . He also leads all rookies in 3-pointers made (51) and has scored at least 25 points in four games.

Duke’s 16th overall pick is one of three Philly players (Kelly Oubre Jr., Guerschon Yabusele) to have played in all 23 games for Philadelphia, whose injury issues have been the defining story of the season.

Stars Joel Embiid, Paul George and Tyrese Maxey have played in just three games together and finished just one – Sunday’s win at Chicago – with everyone on the field.

Embiid, who has played in just six games this season, suffered a ruptured sinus following Friday’s loss to the Indiana Pacers. His status will be reassessed sometime this weekend before Monday’s game in Charlotte.

Philadelphia is 7-16 this season, good for 12th place in the Eastern Conference. They are two games behind the Brooklyn Nets — who are making a deal with the Golden State Warriors to send guard Dennis Schroder to the Bay, sources told ESPN’s Shams Charania on Saturday — for the 10th and final play-in spot -Image of the East.
