Chicago Bulls rookie Caleb Wilson left Wednesday’s game against the San Antonio Spurs with a right hand injury and didn’t return.

The nature of his injury wasn’t initially clear, but the Bulls didn’t take long to rule him out. Wilson sustained the injury in the third quarter and went to the locker room. The Bulls then ruled him out before the start of the fourth quarter.

Wilson has a history of hand injuries. Separate injuries to each hand cut his All-America freshman season at North Carolina short.

A broken bone in his left hand forced him to miss six games midseason. He then broke the thumb on his right hand while dunking in practice, ending his season in March, prior to the NCAA tournament.

The Bulls selected Wilson with the No. 4 pick in June’s NBA Draft. He’s so far delivered on his promise early in his rookie season, with averages of 19.3 points, 6.3 rebounds, 2.1 assists, 1.9 steals and 1 block per game.

His shooting remains a work in progress, as he entered Wednesday’s game shooting 40.6% from the field and 30.4% from 3. He’s developed into a willing 3-point shooter early in his NBA career with 7.7 attempts per game after shooting just 1.1 per game in college.

His further development is a priority the Bulls season, and he’s the centerpiece of their long-term plans. The Bulls are certainly hoping he’s not facing a long-term absence.
