Dustin Poirier could follow Conor McGregor up to welterweight after being called out by Rafael Dos Anjos for an exciting battle of two top former lightweights.
Poirier, who has held interim gold at 155lb and challenged twice for the undisputed belt, has often toyed with the idea of jumping to 170lb. But until now, an obvious fight for him has not arisen at welterweight aside from a grudge fight with Colby Covington that promotional bosses aren't keen to put together.
However, he could be tempted to finally give up the gruelling weight cut to lightweight after being called out by former world champion Dos Anjos, who has reinvented himself up at 170lb. Poirier is keen to put himself in position for a third world title shot, which seems unlikely at lightweight, but could open up doors at welterweight if he can beat Dos Anjos.
