Memphis Grizzlies star point guard Ja Morant has been diagnosed with a Grade 1 sprain in his AC joint, the team announced. The injury is considered week-to-week.

Morant suffered the shoulder injury against the New Orleans Pelicans on Friday night, while the Associated Press (h/t ESPN) reported Saturday that Morant would have his shoulder evaluated.

The guard hurt his right shoulder when he collided with Daniel Theis in the third quarter of Friday's contest. He exited the game and entered the locker room for examinations before returning to the bench but missing the remainder of the game.

Head coach Taylor Jenkins had no initial update but said there would be "more of an evaluation in the next couple days."

Morant missed eight games with hip and pelvic muscle injuries before making his return on Nov. 25 and dropping 22 points and 11 assists in a 123-98 victory over the Portland Trail Blazers.

Through 20 games this season, Morant is averaging 21.2 points, 7.9 assists and 4.4 rebounds. It's the first time since his second year in the NBA that he's averaging less than 25 points.

It was just a year ago that Morant was limited to nine games due to a suspension and subsequent shoulder surgery. He has played in more than 65 games in a season just once in his NBA career, and that was during his rookie year.

Still, Morant is one of the most dynamic and exciting players in the league when healthy. The 2019 No. 2 pick is the top option on a young and talented Grizzlies team that ranks second in the Western Conference with a 22-10 record.

If Morant is forced to miss time, Memphis will rely on star big man Jaren Jackson Jr. to lead the team. Veteran point guard Marcus Smart and emerging youngster Scotty Pippen Jr. would also see more playing time until he's able to return.
