Kamaru Usman (16-1) finished off Colby Covington (15-2) in the fifth round with a TKO victory to retain his welterweight championship Saturday night from T-Mobile Arena in Las Vegas.

Covington came into Saturday’s bout following the most impressive victory in his UFC career, walking through Robbie Lawler en route to a decision victory in which he won every round.

Unbeaten in more than six years, Usman worked his way through the welterweight division in recent years and made good on his first title opportunity with a dominant decision victory over Tyron Woodley in March.

Covington picked up right where he left off against Lawler earlier this year, with an unreal pace to open the bout. For every Usman jab, Covington responded with a slew of combinations.

With about a minute remaining in the first, Usman connected on a stiff uppercut to the body that looked to hurt Covington momentarily.

In the fifth and final round, Covington came out attacking yet again, picking apart Usman with a left jab and uppercut right. Usman finally found his range with about two minutes to go and hurt Covington bad, sending him to the ground twice before earning the TKO victory.
