Former world heavyweight champion David Haye will face Mark de Mori in his comeback fight on January 16.
Haye has not stepped into the ring since stopping fellow Briton Dereck Chisora three years ago, but announced earlier this month that he will be resuming his boxing career.
The 35-year-old Londoner held a press conference at the O2 Arena on Tuesday to reveal that Australian De Mori, 33, will be his opponent at the O2 Arena early next year.
De Mori has won 29 of his 32 fights, losing once and being held to two draws so far in a career which has included 25 knockouts.
Haye said: "It feels really good to be back. Physically, I am firing on all cylinders.
"I have been training with Shane McGuigan and I have got a new lease of life. I have been in the gym working hard and I needed a change from the injuries I got.
"Since I teamed up with Shane, I have gone from strength to strength. Everything has gone through there roof and I feel like a young fighter even at 35."
