Matt Riddle withdrew from his scheduled Bellator MMA debut after suffering a rib injury on Monday.
Riddle, who was slated to fight Luis Melo Jr. in the quarterfinals of the Bellator’s season-nine welterweight tournament, subsequently announced his retirement from mixed martial arts.
“I’m retiring from MMA today,” Riddle wrote on Facebook. “Cracked my rib and can’t fight Sept. 20. Bellator said they can’t find me a fight till the next tournament and I can’t afford not fighting that long and need a job. Sorry if I let anyone down but it isn’t paying the bills.”
