Martin Rogan 'didn't see' final Tyson Fury punch

Tyson Fury stopped Martin Rogan in the fifth round to win the Irish heavyweight championship at the Odyssey Arena in Belfast.

Rogan's cornerman Bernardo Checa stepped through the ropes to call the conest to a halt after 40-year-old Rogan has been floored for a second time by an opponent who was 17 years younger.

Riot police were called to the venue when trouble sparked between groups of opposing fans among the 6,000-strong crowd.

Security on the ground reported a brawl involving around 40 people. Several of the security staff were injured, but not seriously. By the time the police arrived, the trouble had subsided and no arrests were made.
