Memphis Grizzlies forward Jaren Jackson Jr. has undergone foot surgery and could be out for six months.

Jackson was a key man for the Grizzlies in the 2021-22 season, his fourth in the league.

Bouncing back after playing only 11 games (four starts) due to injury the previous year, the former Michigan State man averaged 16.3 points, 5.8 rebounds and 2.3 blocks per game.

He averaged 15.4 points, 6.8 rebounds and 2.5 blocks in the playoffs.

But Jackson has sustained another setback, this time a stress fracture in his right foot, as the team revealed on Thursday.

He underwent surgery on Wednesday – "a successful procedure," the Grizzlies reported – and is expected to miss four to six months. He is expected to make a full recovery.

Jackson suffered a torn meniscus in August 2020, not returning until April 2021. A thigh bruise had previously curtailed his rookie season.
