So tonight sees Selby move up from featherweight to lightweight in his first fight since losing to Josh Warrington in Leeds in May.

Selby says he was so drained at featherweight that he would chew but not swallow food to make weight.

The former world IBF featherweight champion has not fought since losing his title to Josh Warrington last May.

Selby, 32, said he will not consider making the 126lb limit any more, with his first fight at lightweight (135lb) against American Omar Douglas at London's O2 Arena on Saturday.

"The weigh-in days I felt terrible. I could've been seriously hurt. Nine pounds in weight is a big difference in boxing, but it is not a case of 'I get to pack on another nine pounds'.

"The reality is it just means nine pounds less to take off. If you saw my body on the scales last week, you could never believe I was ever able to make featherweight. I don't know how I did it.

"If you offered me £1m to fight at featherweight in a month, I couldn't do it. It wouldn't be possible. I would cry thinking about it."

We'll talk a lot more about DeGale v Eubank later on, but worth mentioning what's going on at the moment and that is Wales' Lee Selby beginning his campaign to become a two-weight world champion. He's in the second round against American Omar Douglas. And Selby has a bad cut over his left eye.

Hello and welcome along to BBC Sport's live text commentary as James DeGale fights Chris Eubank Jr, with a belt on the line - the vacant IBO world super-middleweight title.

Should be a good one.

It is one of the fiercest rivalries in British boxing.

James DeGale, the former IBF world super-middleweight world champion, takes on Chris Eubank Jr at the O2 Arena in London.

Both fighters have two defeats on their records, a third and their career could well be done.
