Sacramento Kings forward Keegan Murray suffered a torn ulnar collateral ligament in his left thumb during a preseason loss in Portland on Friday night, the team announced.
Murray will undergo surgery and be reevaluated in four to six weeks, ruling the Kings' young power forward out for at least the first 10 games of the regular season.
The injury comes at a pivotal time in Murray's career. Entering his fourth season, he is eligible for a contract extension in the next week. The deadline to come to an agreement with the Kings is Oct.
