After they announced his latest fight I'm pretty sure Matt said he retired because he couldn't financially afford to wait for the next tournament to fight after his injury. He said bellator wasn't aware of his situation so they gave him an earlier fight (nathan coy) and fronted him some $ in the meantime to keep him from retiring for real.
Anyways, I wonder if he spent the $, dropped out of another fight, and bellator would have to set up a future fight for him where he doesn't even get a purse (he already got an advance purse) while he keeps dropping out of fights. Sounds like a big headache for the promoter tbh
