Former WBO boxing world champion Joseph Parker's next fight could be against Britain's Dereck Chisora in London in April.
The British boxing promoter Eddie Hearn told website Boxing Social he was trying to arrange a heavyweight clash between Parker and Chisora for the O2 Arena on 20 April.
"I'd like to do four to five big heavyweight fights on the cards and build a big heavyweight night. We'll see where this goes in the next few days."
Hearn is the promoter for British fighters Anthony Joshua and Dillian Whyte, who both defeated Parker last year.
Parker last fought in December, when he knocked out American Alexander Flores in the third round in Christchurch.
Chisora, 35, has had 38 fights during his career, winning 29 of them and losing nine, including twice each against Whyte and Tyson Fury.
His last fight was against Whyte which he lost in an 11th-round knockout in December.
