Illinois forward and Thornton grad Morez Johnson Jr. is out indefinitely after breaking his wrist while making a spectacular block over the weekend.

Coach Brad Underwood announced the severity of Johnson’s injury on Monday. Underwood said the injury occurred when Johnson fell to the floor after blocking a shot during Illinois’ 79-65 loss to No. 14 Michigan State on Saturday.

The injury means Johnson won’t be available Tuesday when Illinois (17-9, 9-7 Big Ten) visits No. 11 Wisconsin (20-5, 10-4).

Underwood said Johnson’s potential return date is uncertain.
