John Joe Nevin maintained his flawless pro career with victory against Greg Coverson Junior in Hammond, Indiana in the early hours of Thursday morning.

Nevin, an Olympic silver medallist at London 2012, went the distance with 36-year-old Coverson, winning by judge’s decision.

The Mullingar lightweight earned a routine victory over DeWayne Wisdom in Virginia nine days ago, but didn't have it all his own way against the seasoned Coverson, ultimately getting the decision after six rounds at the Hitz Boxing Fight Night at the Horseshoe Casino, just outside Chicago.

Nevin has now won four fights in just three months, while Coverson is without a victory in over five years.

Mike 'Hollywood' Jimenez won his NABA Super Middlewight Championship bout against Dezi Ford in the card's headline fight.
