The Chicago Bulls will be without their star rookie for the foreseeable future.

He suffered the injury in a loss to the San Antonio Spurs on Wednesday, exiting the game after 15 minutes of action, leaving the contest with 15 points, five rebounds and a steal on 5-of-7 shooting.

The UNC product leads Chicago in average minutes, field-goal attempts and steals, while ranking second in points and rebounds. He recently tied NBA legend and Bulls icon Michael Jordan as the fastest player in franchise history to reach 100 career points (five games) and surpassed Derrick Rose’s mark of 166 points through his first nine games.

Wilson leads all rookies in steals per game, ranks third in scoring, fourth in rebounds and sixth in minutes.

The 1-9 Bulls return to action on Friday, hosting the Atlanta Hawks.
