Mike Brown rose to prominence in the WEC, securing the promotions title.

Brown, however, might be finished fighting inside the Octagon, as he recently underwent a second neck fusion surgery, according to a report by MMA Weekly.

For now, while he rehabs, Brown will serve as a full-time assistant coach at American Top Team. ATT released a statement:

He will see how his rehab goes and take it one day at a time. He hasn’t ruled out fighting in the future.

Brown has won each of his last two UFC fights, and recently signed a five-fight deal with the promotion. He is 26-8 in his career, including several thrilling bouts with the likes of Urijah Faber.
