COLBY COVINGTON STAKED a strong claim for another shot at the welterweight title by overcoming former champion Tyron Woodley in the main event at UFC Fight Night 178.

Following considerable animosity between the fighters in the build-up to the bout, Covington was dominant when they finally squared off at the UFC’s Apex facility in Las Vegas.

According to all three judges, Covington won every round – including a 10-8 score in the fourth – before stopping Woodley in slightly unusual circumstances in the fifth.

Having been taken down against the cage, Woodley was searching for a guillotine choke when he let out a scream. The fight was soon waved off by referee Dan Miragliotta, with Woodley later revealing that he had sustained a rib injury.

Afterwards, Covington called out welterweight champion Kamaru Usman, by whom he was beaten via fifth-round TKO last December.

Elsewhere on the card, veteran Donald ‘Cowboy’ Cerrone fought to a majority draw with Niko Price, after undefeated prospect Khamzat Chimaev – competing in the octagon for the third time in nine weeks – needed just 17 seconds to defeat Gerald Meerschaert with a one-punch KO.

There was also a first-round KO win over Ryan Spann for Brazilian light-heavyweight Johnny Walker, who had SBG Ireland head coach John Kavanagh in his corner as he continues to fight out of the Dublin gym.
