Sean Monaghan

Sean Monaghan is an American professional boxer in the Light Heavyweight division. He fights out of Long Beach, New York.

Before he was a professional boxer, he had a job as a bricklayer, where he worked assembling sidewalks and buildings. His parents are from County Meath, Ireland.

Monaghan had about 15 amateur fights.

Before deciding to join the pro ranks, Monaghan competed in the 2009 New York Golden Gloves competition, losing at the final on points, at Madison Square Garden.

Monaghan made his professional debut in his hometown. He faced Simeon Trigueno. A body shot sent Trigueno down to a knee for an eight count. He beat the count but was dropped again by a straight right hand to the head and was saved by the bell to end the round. The ringside doctor put an end to the bout citing an injury. Monaghan was credited with a first round TKO.

Monaghan scored a fifth round TKO over Anthony Pietrantonio in the Garden’s WaMu Theatre on October 22, 2011.

On June 14 in front of a capacity crowd at NY's Roseland Ballroom, Monaghan became the new WBC Continental Americas Light Heavyweight Champion with an 8th round TKO over Romaro Johnson

Monaghan has been working on sharpening his technique with greater emphasis on speed, head movement and combination work as opposed to merely looking to land the devastating kill shot, although he still possesses a keen ability to score knockouts.

Monaghan appeared on the undercard of the WBO featherweight championship fight between Orlando Salido and challenger Mikey Garcia at Madison Square Garden Theater on January 19, 2013 where he defeated Roger Cantrell by unanimous decision in an eight-round fight.

On the April 13th Donaire-Rigondeaux undercard at The Radio City Music Hall Monaghan scored a first-round knockout of journeyman Dion Stanley (overhand right). This knockout propelled his career - convincing Top Rank Boxing's Bob Arum to sign the popular fighter.
