Super middleweight contender John Ryder has confirmed that he's flying out to Dallas, but highly doubts that he'll replace Billy Joe Saunders in the upcoming clash with Mexican superstar Saul 'Canelo' Alvarez.

Saunders and Canelo are scheduled to collide on Saturday night for the WBC, WBA, WBO world titles at the AT&T Stadium in Arlington.

There is currently an ongoing dispute between Saunders and Canelo - with the the British champion threatening to withdraw over the ring size.

He doesn't want to give off the impression that he's flying over for the sole purpose of potentially replacing Saunders.

Even before the ring size row began, Ryder was already scheduled to fly out to the Dallas to promote next month's fight with WBA "regular" champion David Morrell.

Ryder highly doubts Saunders will actually follow through with his threat to withdraw.

But, just in case, Ryder will pack his necessary fighting gear.

"I think it's smoke and mirrors," Ryder told Sky Sports. "I think he's going to get what he wants. I was always due to go out to Dallas. Eddie wanted me to get out there and do a bit of promotion, for my up and coming fight in June, so I was always heading out there. But I mean if he gives me the call, I'll pack the gum shield and protector. Listen, I'd do it outside the pub on a Saturday night for free, so put a bit of financial motivation behind it, definitely.

"Very small [chance I'll step in for Saunders]. You don't come this far in a fight to let it go at the last minute, because of a couple of foot. It's something that should have been settled at the start of negotiations. One of the first things. Sort out your purse, sort out the ring, sort out whether you are walking first or second, or whatever. It should have been tied up ages ago.

"It's silly that it's come on fight week really. Is it just mind games? I don't think Canelo is the person to do mind games with, but I think Billy Joe has got a few tricks up his sleeve. Billy is his own man, he doesn't really dance to anyone's tune and he does as he wants. I wouldn't want to step in and take a pay day away from him, because they think I'm going out there for that. I'm purely going out there to promote myself, get my name out there a bit for my fight.

"This has suddenly come on me this afternoon that there is an issue with the size of the ring and it just so happens that I'm going out there. Eddie has not made any contact but I'm taking my gloves out there and my boots, because I want to do a bit of pad work while I'm out there. I would gladly oblige if he [Canelo] wants to give away a couple of pounds."
