UNLV forward Mike Moser suffered a dislocated elbow early in the first half of Sunday's game against California.
Moser, a First-Team All-Mountain West selection last season as a sophomore, was chasing after a loose ball and had a Cal player fall on his elbow. He was seen holding his arm as he made his way into the locker room.
When the 6-foot-8 forward returned to the bench, he had his arm in a sling and his return from the injury is not yet known.
Moser, who missed UNLV's previous game with a hip injury, was the team's leading rebounder at 9.2 boards per game while averaging 12.3 points over his first six games.
