Portland Trail Blazers guard/forward Matisse Thybulle injured his left thumb during Wednesday’s game at Utah. A subsequent MRI conducted Thursday revealed a tear of the ulnar collateral ligament (UCL) of the left thumb.

Thybulle underwent successful surgery this morning which was performed by Steven S. Shin, MD at the Cedars Sinai/Kerlan-Jobe Surgery Center in Los Angeles, California and will be re-evaluated in 4-6 weeks
