Jai Herbert will get a shot at the big leagues.

Herbert (10-1 MMA, 0-0 UFC), the Cage Warriors lightweight champion, has stepped in to replace an injured Stevie Ray (23-9 MMA, 7-4 UFC) to take on Marc Diakiese (14-3 MMA, 5-3 UFC) in a lightweight bout at UFC on ESPN+ 29. MMA Junkie confirmed the booking with a person with knowledge of the matchup following an initial reported from Newsome.
