Clarkson is questionable for Wednesday's game against the Grizzlies due to a right thigh contusion, Andy Larsen of The Salt Lake Tribune reports.
It's unclear when Clarkson picked up the injury, but he appears to have moved past the illness that caused him to miss a game last week. If the veteran guard is ruled out, Talen Horton-Tucker, Kris Dunn and Simone Fontecchio are candidates to receive increased minutes.
