Kell Brook says he will announce his retirement in the ring if he loses to Mark DeLuca on 8 February.
Brook, 33, will face the American after a 14-month spell out of the ring.
Sheffield’s Brook has endured a testing period since 2016, having broken both eye sockets and given up his world welterweight title.
“This last chapter of my career, I’m giving it my all,” Brook said. “If I get beaten I can walk away with my head high, knowing I have given everything.”
He told the 5 Live Boxing with Costello & Bunce podcast: “If I get beaten by DeLuca, I will announce my retirement in that ring. If I can’t beat him, what am I doing?”
