(CNN) With his NFL career apparently over, receiver Antonio Brown has enrolled in online classes at Central Michigan University to finish his college degree.

Central Michigan confirmed that Brown is currently enrolled in online degree completion coursework at the university. The online courses began last week. Brown does not attend classes on a CMU campus, CMU said.

Brown attended Central Michigan for three years before foregoing his senior year to enter the NFL.

The 31-year-old has plenty of time to complete the classes after he was released by the New England Patriots last week -- his third team in a year.
