MOUNT PLEASANT, Mich. (WOOD/AP) — A day after announcing he was leaving the NFL during a Twitter rant, former wide receiver Antonio Brown appears to be heading back to school at Central Michigan University.

On Instagram Monday, the CMU alum posted an image of a course schedule for the fall semester with the message “back to school,” tagging CMU’s athletics department.

All four courses are taught online. They include introduction to management, technical writing, a religious course on death and dying and a social studies course on racism and inequality.

A Sept. 23, 2019 screenshot shows the Instagram story post from Antonio Brown’s account, hinting to his return to Central Michigan University.

In a Monday statement, CMU confirmed that Brown is enrolled in online classes that started last week and emphasized that he doesn’t attend classes on campus. It said it would track Brown’s legal cases and “follow our policies and procedures, as we do for all our students.”

In January, CMU recognized Brown for donating $105,000 worth of heated football benches to the school. The university also gave a nod to Brown’s contributions on the field, including two MAC championships while playing for the Chippewas.

On Twitter Sunday, Brown announced he “Will not be playing in the NFL anymore” and claimed the league had been more lenient toward others facing allegations of sexual misconduct.

The once-prolific wide receiver was traded out of Pittsburgh and released in Oakland after wearing out his welcome in both cities.

The Patriots signed him after that, but days later a former trainer filed a civil lawsuit in Florida accusing him of rape.

Brown played in one Patriots game then was released after the team learned he tried to intimidate a second woman who accused him of sexual misconduct.

Brown’s first tweet on Sunday seemed to indicate that he will fight the Patriots’ decision to withhold a $9 million signing bonus.

Central Michigan’s full statement on Brown:

“Antonio Brown is currently enrolled in online degree completion coursework at Central Michigan University. He does not attend classes on a CMU campus. His online courses began last week.

“CMU is monitoring media reports and following the investigation and civil litigation. We will follow our policies and procedures, as we do for all of our students. Central is a leading university in raising awareness and prevention of sexual assault, and it provides students, faculty and staff with a variety of resources and counseling services.”
