Dillian Whyte's heavyweight showdown against Alexander Povetkin has been rescheduled for Saturday, July 4, after all British boxing events in May were called off because of the coronavirus pandemic.
The British Boxing Board of Control announced on Monday it had extended its suspension of all shows under its auspices, having initially shut down everything in April.
Whyte was due to face Russian veteran Povetkin on May 2 at the Manchester Arena, where Ireland's Katie Taylor would have put her status as undisputed lightweight champion on the line against seven-weight titlist Amanda Serrano.
However, Matchroom announced the bill will now go ahead at the same venue on the first weekend in July "subject to the developing situation".
Welsh fighter Lee Selby's IBF lightweight title eliminator against George Kambosos Jr at the Motorpoint Arena Cardiff on May 9 has been put back to July 11.
Matchroom says tickets already bought for the new dates will still be valid while refunds will be made available from the point of purchase.
Meanwhile, Matchroom confirmed it is attempting to rearrange a blockbuster heavyweight bout between Dereck Chisora and former undisputed cruiserweight champion Oleksandr Usyk, originally slated for May 23 at London's O2 Arena.
