Paddy Donovan TKO4 Tyrone McKenna... Paddy Donovan defeated Tyrone McKenna in an all-Irish welterweight encounter at Dublin's Croke Park. Donovan scored a knockdown and then piled on the pressure after opening a bad cut above McKenna's right eye. The doctor called it off in round four. Donovan improves to 16-2, while McKenna falls to 25-7-1. After narrowly losing an IBF championship shot to Lewis Crocker last year, another world title opportunity should be next for Donovan.
