Nathan Cleverly has called time on his boxing career after losing his WBA light-heavyweight title to Badou Jack.
The 30-year-old Welshman surrendered his belt following a fifth-round stoppage on the undercard of Floyd Mayweather Jr's super-fight against Conor McGregor.
Cleverly took to Twitter to announce his retirement in the wake of his fourth career defeat.

"Time to say goodbye. Thank you and goodbye boxing," he wrote.
"I've lived it and loved every second of this sport. A few too many miles on the clock."
Cleverly had held his WBA title since October last year when he defeated Juergen Braehmer.
