Perennial contender Dustin Poirier has weighed in on Ilia Topuria's lightweight move. The former UFC interim lightweight champion used to be a featherweight like Topuria, moving up to 155lbs after a 2014 loss to Conor McGregor before hitting his stride in the years that followed.

Dustin Poirier gives his reaction to Ilia Topuria moving up to his division after vacating the UFC featherweight title.

Dustin Poirier says Islam Makhachev could make a lot of noise at welterweight but not so much going all the way up to 185 pounds and the same goes for Ilia Topuria trying to claim the lightweight titl
