The heavy-handed slugger just recently picked up another big win as he submitted Josh Barnett in the first round at FOX UFC Fight Night in New Jersey, stomping ever closer to a title shot.

Rothwell has looked virtually unbeatable lately, but he'll have to go through a former champion if he wants to extend his streak and stay on the path for a title shot.

Dos Santos will not only look to beat Rothwell in April, but also find some redemption after falling to Alistair Overeem in his last fight.

Dos Santos was plagued with injuries throughout 2015, but when he finally returned the Brazilian got a rude welcome from Overeem, who knocked him out in the second round.

Dos Santos has bounced back and forth between wins and losses over his past six fights, but now the former champion will look to start fresh in 2016 with a victory over one of the best heavyweights in the world.
