Luke Campbell says Vasyl Lomachenko world-title bout not yet confirmed
Britain's Luke Campbell has denied he has signed to challenge unified world lightweight champion Vasyl Lomachenko in the UK on 31 August.
On Tuesday, the WBC tweeted to confirm the bout, which would see Lomachenko, 31, risk his WBO and WBA belts, with the vacant WBC title also on the line.
But on Wednesday, Campbell, 31, wrote on Instagram: "Don't believe everything you read on social media.
"The fight is not confirmed yet. Stay tuned, real fight news coming soon."
Campbell would be a massive underdog if he does face Lomachenko in what would be the Ukrainian's first bout in the UK.
The contest would see two Olympic gold medal winners facing one another as Campbell won gold at bantamweight in 2012, while Lomachenko claimed the featherweight title in 2008 and lightweight in 2012.
Lomachenko built a reported amateur record of 396 wins and one loss before turning professional and lost a world-title shot in his second bout.
But he recovered to amass world titles and became the quickest three-weight world champion in history when he beat Jorge Linares in May 2018.
In all, Lomachenko has held world titles at featherweight, super featherweight and lightweight, and holds a record of 13 wins and one defeat.
Campbell has fought for a world title once before but lost a split-points call to Linares in 2017 and revealed afterwards he had hidden the fact his father had died two weeks before the bout.
Campbell's record now reads 22 wins and two defeats, including three wins since his defeat to Linares.
