Mike Tyson dropped a new video of himself training on Instagram Monday, and at the end of the short clip he declared, “I’m back!”

Yardbarker reports that the 53-year-old captioned the post, “Anything is possible when you are smart about it. Train Smart. Recover Smarter..”

Whether Tyson is seriously considering a return to the ring is unclear, but something seems up, as reports about Tyson have been circulating in recent months.

In April, he said he wanted to participate in exhibition contests to raise funds for charitable causes. Major League Wrestling and Australian rugby stars have reached out to him about potential match-ups.

Evander Holyfield has also said he’d be willing to step inside a ring with Tyson to complete a trilogy of bouts.
