WATCH | Paddy Donovan wins by KO 78 seconds into pro debut

Take a bow Paddy Donovan.

The 20-year-old Irish welterweight has announced himself on the professional stage with a stunning first round knockout at Ulster Hall.

Donovan stopped opponent Arturo Lopez with a ferocious left hand after just 78 seconds, much to the delight of the Belcast crowd.

Lopez required attention for several minutes following the knockout, receiving oxygen and leaving the ring on a stretcher.

Donovan was fighting on the undercard of Paddy Barnes’ disappointing defeat to Jay Harris.

Donovan amassed a record of 161-5 at amateur level, and was a 13-time underage national champion.

The Limerick native looked confident and composed on his way to the ring, and justified the hype around his move to the professional ranks with a devastating performance.
