Chris Eubank Jr. insists that he won't squeeze down to 155-pounds for a potential fight with Kell Brook.

Both boxers are very interested in the fight, but they are unable to agree on the contracted weight more than anything else.

Brook, who last month stopped career rival Amir Khan at a catch-weight of 149, wants the contest with Eubank to be held at 155.

Eubank, who competes at the middleweight limit of 160, says there is no way for him to safely make the requested weight.

Promoter Ben Shalom of BOXXER would like to stage a Brook vs. Eubank showdown on a July pay-per-view date.

Brook fought at the middleweight limit in 2016, when he challenged middleweight champion Gennadiy Golovkin. The hard punching Golovkin stopped Brook in five rounds.

Eubank argues that Brook walks around at a heavier weight and rehydrates to higher limits on fight night, too.

“I like how people talk about how he could probably make it down to 155 if he tried really hard. The guy walks around at 180-pounds. He walks around heavier than I do. He fought Gennady Golovkin at 160 and got into the ring at 168 on the night," Eubank told Talk Sport.

“When I fight at 160, the maximum I put on is five pounds. He will be bigger than me on the night if we fight at 160. People are talking about me coming down to 155, that’s just not going to happen. I’ve never fought at that weight before and I don’t have that much weight to take off. He would comfortably make 160. Could I shave off a couple of pounds if I had to? Yes, but one or two maximum. 155 is not happening, 158 at a push. If that can’t be agreed on then we’ve got much bigger fish to fry and it’s not the end of the world.”
