THE mouthwatering lightweight showdown between Gervonta Davis and Ryan Garcia is in major doubt.
The 135lb sensations were on course to throw down in a Las Vegas super-fight on April 15 after Davis' win over Hector Garcia last month.
But negotiations have hit a snag as both parties are squabbling over who will be the A-side should a rematch come to fruition.
Golden Boy Promotions chief Oscar De La Hoya told ESPN: "It boils down to who's going to control the rematch.
"We're literally down at the 1-yard line; what's holding everything up is the rematch clause.

"It's only fair if Ryan wins, then our side controls everything as the A-side.
"This is just the way it always has been. … It's common sense that whoever wins is the A-side.
"That's the bottom line. We're not reinventing the wheel here."
Broadcasting rights are a small part of the rematch quarrel, with the PBC and Showtime adamant they should retain them if a rematch happens.
De La Hoya said: "Al Haymon is dictating everything. … They've asked for this, asked for that.

"Who comes out first, the penalties if Ryan comes overweight.
"We've given in, we've negotiated, and everything has been very pleasant.
"If Ryan loses, sure, there's no rematch.
"It's been a pleasant negotiation, it really has. I really hope their side doesn't fumble the ball and we have no Super Bowl.

"We at Golden Boy are just protecting our TV partners.
"It's only fair that everything gets switched around if Ryan wins."
Despite the current roadblock, De La Hoya is hoping the fight will get made.
He said: "We're holding strong because we know it's fair and we feel 1,000% this fight is going to be made and be the biggest fight of the past few years."
