Super-welterweight Tyrone Brunson caused something of a shock at the 2300 Arena in Philadelphia with a fifth round stoppage of former world champion Kermit Cintron.
Brunson, who once held a record of 19-0 with 19 first rounds knockouts, proved the power was still there as he recovered from being dropped twice in the fourth to halt the 37 year-old veteran.
Cintron, an ex-IBF welterweight title holder, seemed on the way to victory until Brunson turned the fight on it’s head to secure the upset. Brunson improves to 25-6-2 as Cintron drops to 39-6-3 and will need to consider his options.
