Adrien Broner, Gervonta Davis and Jermall Charlo make up a trans-Atlantic treat this Sunday morning, live on Sky Sports.
On the back of Amir Khan's British homecoming in Liverpool on April 21, attention will then turn to the Barclays Center, New York, where the fast-talking American trio will complete an action-packed night, live on Sky Sports.
He is still just 28, but already there is a sense of the twilight years shrouding four-weight world champion Broner. The brash Cincinnati native remains one of the sport's great enigmas, undoubted ability in the ring but natural talent hampered by a flashy, audacious, persona outside it.
'The Problem' needs to prove he still has a lot left, his spiral towards becoming an elite level gatekeeper needs to be backtracked, and victory over two-weight world champ Vargas will quash any theory Broner is in decline.
Vargas, by way of Las Vegas, has a fine record with victories over the likes of Sadam Ali and Antonio DeMarco. He has provided solid opposition in decision defeats to Manny Pacquaio and Timothy Bradley, the only blemishes on his record, and now he is just as ready to reignite his career.
Floyd Mayweather's dazzling protege is back in action as Davis tackles hard-hitting Argentinian and former world champion Cuellar for the WBA 'Super' super-featherweight world title.
'Tank', 23, seemed to have the world at his feet after he burst onto the scene in emphatic fashion in stopping Jose Pedraza back in January 2017, but weight issues since have marred and slightly stalled what is expected to be an outstanding career.
Davis returns to New York, the scene of that astounding Pedraza victory, and the Baltimore star will want to prove he can not just make the weight but do so in style.
The rise of the Charlo brothers is showing no signs of stopping and, with Jermell regularly defending his WBC title down at super-welterweight in scintillating fashion, twin Jermall's quest for two-weight glory is well and truly underway.
With 26 wins from as many fights, Charlo has blown away everyone in his path and sits on the cusp of a mega fight at middleweight with Gennady Golovkin, 'Canelo' Alvarez, Danny Jacobs and Billy Joe Saunders lying in wait.
The Texan puncher will face Centeno Jr for the interim WBC world title - the full version currently held by Golovkin - so victory will prime him for a shot at 'GGG' or possibly a chance to end his verbal feud with Jacobs who fights a week later, live on Sky Sports.
The triple-header from the Barclays Center will be live on Sky Sports Main Event and Action from 2.00am on Sunday, but you can also find out what happens via skysports.com, the Sky Sports mobile app and @SkySportsBoxing on Twitter.
