Teofimo Lopez has claimed that he will be the undisputed champion at 140 pounds.

Lopez took the pledge on Twitter and wrote: “I will be UNBEATED again but in Junior welterweight! # The takeover”.

The American fighter was the united – and some would argue undisputed – champion at lightweight until he met George Kambosos Jr. in November last year. The Australian got a big surprise to win, but Lopez’s father said he had made a mistake when he held back his son to continue fighting at 135 pounds.

The pair had previously suggested that they could move up to 140 pounds earlier because they were looking for high-profile match-ups, and now it seems that Lopez Jr. is ready to embark on the hunt for a new four belts.

If Lopez wants to return to winning titles in a short time, he will have to arrange a match with current undisputed champion Josh Taylor, who will face Jack Catterall on February 26 in a WBO mandatory defense in Glasgow.

Taylor, for his part, has suggested he is ready to move to £ 147 in his next fight, with a fight against Terence Crawford or other title holders suggested by the Scots, although he could be persuaded to remain in superweight if he can secure money -spinning with Lopez.
