Anthony Joshua could be one fight away from a world title bout after being offered an IBF eliminator fight against Carlos Takam.
Commonwealth champion Joshua is causing a stir in the heavyweight division, having won his first 15 fights as a professional.
Erkan Teper is above the Brit in the pecking order for a shot against IBF champion Charles Martin, but has tested positive for a banned substance and the organisation are waiting for a B sample test before sanctioning Joshua vs Takam – the winner of which would become the mandatory challenger.
"Teper and Takam are the next two, but if there is a problem with either one, we would go to Joshua," IBF championships chairman Lindsey E Tucker told Sky Sports.
"If Teper is out, yes it will be Takam and Joshua. They will be fighting for the No 1 position, which is the mandatory challenge.
"We would give them the standard 30-day negotiation period and then if they did not reach the decision we would call for a purse bid."
Takam is much more experienced than Joshua, having recorded 33 victories, although he has been beaten twice.
Joshua, who knocked out Dillian Whyte at the O2 Arena in December, is a target for a number of fighters in the division, and the 26-year-old is prepared to take on whoever stands in his way.
"I can't wait to get back in the ring on April 9," he said. "I feel fit and ready to take on whoever I need to continue my journey to the top.
"The atmosphere at the O2 was unbelievable in December so I'm looking forward to putting on an even bigger show for the fans. It is a really exciting time for heavyweight boxing right now so I can't wait to get fighting."
