Islam Makhachev submitted Dustin Poirier in the fifth round of a gruelling contest to retain his lightweight title at UFC 302 in New Jersey.

Russian Makhachev's elite grappling proved the difference as the 32-year-old secured a d'arce choke, forcing American Poirier to submit.

The victory at the Prudential Centre was Makhachev's third defence of his belt while Poirier, 35, hinted at retirement after coming up short in what is likely to be his final attempt at becoming undisputed champion.
