Memphis Grizzlies rookie center Zach Edey exited during the second half of Sunday’s win over the visiting Denver Nuggets with a left ankle injury.

Edey, the ninth overall pick of June’s NBA draft, initially injured his ankle during the first half before re-aggravating it after halftime. He left with Memphis up 80-62 with 1:10 remaining in the third quarter and did not return.

Edey finished with seven points, seven rebounds, two assists and two blocks in 14 minutes off the bench as the Grizzlies went on to win 105-90.

The former Purdue standout is averaging 11.1 points, 6.9 rebounds and 1.0 blocks in 20.1 minutes across 14 games (nine starts) for Memphis.

The severity of Edey’s injury is not yet known. Edey, who stands 7-foot-4, previously battled ankle issues during NBA Summer League play.

Memphis is already playing without star guard Ja Morant, who remains out with a hip injury he sustained on Nov. 6. Grizzlies coach Taylor Jenkins said that Morant will be reevaluated on Monday.

Memphis hosts Denver again on Tuesday.
