CHRIS EUBANK JR will fight Anatoli Muratov on Saturday after Sven Elbir’s positive coronavirus test.
Muratov has stepped in at late notice to ensure Eubank Jr, 32, gets his fight at Wembley Arena.
The Brit has emerged as one of the middleweight division’s top contenders.
And Eubank Jr will be hoping another win puts him in line for a chance at the WBA title this year.
But it won’t be easy against Muratov, who is ranked No7 in the world and has won 24 of his 27 fights.
A super-fight with Gennady Golovkin, 39, is parked until the summer, with the Kazakh due to fight Japan’s Ryota Murata, 35, in a unification.
Promoter Kalle Sauerland promised a massive pay-per-view worthy fight will come before the year’s out, should any slip ups be avoided.

Sauerland told SunSport: “Golovkin I can categorically rule out, Golovkin right now is obligated to fight Murata.
“That is an ongoing one, something we said we would re-visit when he’s had that fight. That’s going to be a big summer one for next year.
“We’re looking at domestic fights, Liam Williams is on that list, Billy Joe is on that list.”
Eubank Jr was bitterly beaten by Saunders on a split-decision in 2014.
The result failed to settle their score and has instead only intensified their rivalry, fuelling demand for a rematch.

Sauerland added: “I’m sure it will happen. Billy Joe said he was considering his future, but now he wants to fight him.
“Before it was, ‘OK, is he going to fight again?’ He’s made a lot of money, you wouldn’t have any qualms about him retiring.
“But he said he wants that fight and of course, we’re going to make that fight happen.”
