Devin Haney and Jorge Linares will clash for the WBC lightweight title on Saturday night in Las Vegas in a huge 130-pound dust-up.
The American youngster is one of the hottest prospects in US boxing and is hoping to make a successful defence of his title in this one.
Meanwhile, challenger Linares has won world championships in three weight classes before and will be hoping to roll back the years at 36. But he faces a tough task against Haney, who is the overwhelming favourite heading into this one.
If Haney wins, he is eyeing an all-American clash with Ryan Garcia later this year, a fight which would undoubtedly capture the attention of fight fans on both sides of the Atlantic.
