Tyson Fury's rematch with Deontay Wilder is unlikely to happen until 2020, according to the British fighter's U.S. promoter Bob Arum.

Fury made his return to the big stage in December's heavyweight title bout against Wilder in Los Angeles, the lineal champion getting up from two knockdowns at Staples Center.
A split decision after 12 rounds produced a controversial draw, and a rematch was ordered by the WBC for 2019.
However, the pair were unable to agree a deal to meet again, and both have different opponents lined up this year.
Wilder will put his strap on the line against Dominic Breazeale in May, and Fury will face Tom Schwarz in Las Vegas in June.
Getting Wilder and Fury back in the ring together remains the plan, but Top Rank's Arum says fans will have to wait a little longer.
"Assuming he [Fury] wins this fight [with Schwarz], he'll have another appearance in the United States," he told World Boxing News.
"Then hopefully next year in February he'll end up fighting Wilder."
