The 40-year-old Soliman (44-11, 18 KOs) will be making his first title defense since outpointing Felix Sturm on Sturm's turf in Germany to claim the belt by unanimous decision in May. The fight was a rematch of their February 2013 title eliminator, which Soliman won by unanimous decision. However, the result was changed to a no contest because Soliman failed his post-fight drug test and was suspended for nine months by German regulators.
Kurt Emhoff, an attorney and Soliman's and co-manager, said Soliman has signed for the fight, deciding to fight Taylor rather than accept a unification fight against Gennady Golovkin that was also on the table.
"We got a very generous offer for this fight," Emhoff said.
Emhoff said he was "pretty far along in negotiations with Golovkin" even before Golovkin's third-round destruction of Daniel Geale on July 26, but he said he could not close the deal with Golovkin promoter Tom Loeffler of K2 Promotions because the fight with Geale had not happened yet.
"They had the Geale fight coming up and we had to wait a little bit and then this offer came in and it blew the (offer for the) Golovkin fight out of the water," Emhoff said. "It took Sam (17) years to win a title. He has fought everybody, but he's going to be 41 and he was looking for the best possible financial package that was offered and that's what we took.
"Jermain is ranked by the IBF, he's a big name, he's won four fights in a row and he beat Truax. So we know we have to be ready and we expect the best Jermain Taylor. He was seconds away from beating Froch. We're taking him seriously. He's a tough out for anybody."
