American boxer Deontay Wilder will defend his WBC heavyweight title against Luis Ortiz at New York's Barclays Centre in March.
In taking the fight with fellow unbeaten fighter Ortiz, Wilder has accepted what is widely considered his greatest test yet.
He will be making the sixth defence of his title on March 3 having in November stopped Bermane Stiverne, when a match-up with Ortiz was cancelled after the 38-year-old Cuban tested positive for banned substances in a drugs test.
Ortiz avoided a ban after the WBC found he had taken diuretics for high blood pressure, although he was fined.
The fight will be Wilder's seventh defence of the WBC heavyweight world title.
