Now that Antonio Brown has decided to stop playing football, the All-Pro wide receiver has some time on his hands. It appears that he’s going to do something constructive with it.

Brown, who was released by the New England Patriots on Friday, took to his Instagram Story to reveal that he’s going back to school.

“Back to school,” Brown wrote, sharing a photo of his class schedule that includes four courses.

Brown tagged Central Michigan in the photo, seeming to indicate that he’s going back to the place he played college football.

Brown played at Central Michigan from 2007-09. He left school after his junior year to declare for the NFL Draft. Brown had 110 receptions, 1,198 receiving yards and nine touchdowns his final year.

The former Patriots wide receiver announced Sunday morning that he was done playing in the NFL.

“Will not be playing in the NFL anymore these owners can cancel deals do whatever they want at anytime we will see if the NFLPA hold them accountable sad they can just void guarantees anytime going on 40m 2 months will see if they pay up!” he announced.

The NFL has said that Brown could be placed on the exempt list if he ends up getting signed by another team. It’s reportedly unlikely that Brown is going to be signed by another team until his legal situation is cleared up.
