The scheduled Oct. 29 defense of Artur Beterbiev's three light heavyweight championships against Anthony Yarde has been postponed due to an injury, a source told ESPN. The type of injury wasn't made public.

The battle is expected to be rescheduled for early 2023, according to the source, and was originally supposed to take place in London's O2 Arena after an agreement was reached.

The news was initially released by BoxingScene.

In June, Beterbiev (18-0, 18 KOs) defeated Joe Smith Jr. in the second round to win his third 175-pound championship. The 37-year-old Russian-Canadian is the first boxing champion to have won by stoppage in each of his professional contests.

At 175 pounds, Beterbiev is the No. 1 boxer on ESPN, and he ranks No. 7 pound-for-pound.

In a rematch in December, Yarde (22-2, 21 KOs) knocked out Lyndon Arthur in the fourth round to avenge a loss from 2020 and earn a shot at the crown.

The 31-year-old Londoner's lone title fight in 2019 ended in a TKO loss to Sergey Kovalev in the 11th round.
