Wendell Carter Jr. sustained a left thumb injury in the game at the Los Angeles Lakers on Jan. 15. A MRI was performed the next day in Los Angeles, with the initial diagnosis of an acute on chronic thumb sprain. He was examined today by Bulls hand specialists, Drs. John Fernandez and Mark Cohen. Repeat physical examination, testing under live fluoroscopic XR, and review of all tests determined the extent of the thumb injury and associated instability. Surgery is recommended with an anticipated recovery and return to sport time of 8-12 weeks.
