The Memphis Grizzlies’ matchup against the Denver Nuggets tonight took a sudden turn. Sophomore center Zach Edey exited the game in the first quarter and did not return. There wasn’t any immediately obvious moment that stood out, but concern quickly rose for the 23-year-old.

Soon after, Memphis provided some clarity. Grizzlies insider Damichael Cole reported, “Grizzlies say Zach Edey is doubtful to return tonight (head).” This confirmed that the team’s starting center and key interior rebounder is dealing with a head injury, but the extent of it was not known. Shortly afterwards, he was ruled out of the game.

After the game, head coach Tuomas Iisalo explained that Edey was hit in the head and ruled out, but that’s all he knows. Before exiting, Edey had been a steady presence, recording 2 points and a rebound. He was a key defender on Nuggets superstar Nikola Jokic, and his presence was sorely missed, as Jokic proceeded to drop 17 points, 10 rebounds and 16 assists.
