Trainer David Coldwell has confirmed that Jamie McDonnell’s rematch with Liborio Solis will be the WBA world champion’s last fight at bantamweight, win or lose.
Whatever the result against Solis, this will be Jamie's last fight at bantamweight.
This isn't a case of looking past the Venezuelan or chasing anyone else, our full focus is on this rematch and Jamie has the mindset that everything is on the line, but win, lose or draw, we go up in weight.
I've been saying for a few years now that he should move up and this is the first time that Jamie has turned around and agreed with me. He just realises that it needs to happen and said to me: "We will move up."
He wants to be at his best and he knows that another four pounds on him at super-bantam or even going further up to featherweight will get the best out of him.
You have to remember that Jamie has been making bantamweight for a long, long time, most of his career, and although he's achieved a lot, he's getting older and he knows that he is coming towards the end.
He would like to step up to super-bantam to get a world title or even mix it at feather, he wants those big juicy fights.
The likes of Scott Quigg, Carl Frampton are massive superstars and Jamie wants to be in those sort of fights, but more importantly, he has to be performing at his best.
Obviously, though, we are by no means looking past Solis and this is a very tough fight, Jamie is well aware of how powerful and dangerous he is and Jamie is well up for this one.
I think that the difference for this rematch is Jamie's state of mind. After his two wins over Tomoki Kameda, Jamie wanted the big names and the biggest fights, ones he could really get his teeth into.
Jamie hadn't heard of Solis so mentally he thought it would be a routine defence. I had explained time and time again who Solis was and what he had already achieved, but sometimes fighters, when they are waiting for big fights, they struggle to get up for other challenges.
We did pick Solis as a voluntary because we wanted a tough test, but still Jamie didn't really switch on.
Now though, he knows the deal, he knows how everyone reacted to the first fight and this is massive for him - he is more motivated than ever.
This is the toughest fight and probably the most important of Jamie's career. All eyes are on it because of the first time around and we have prepared accordingly, everything is on the line.
