The heavyweight fight between Wladimir Klitschko and Tomasz Adamek appears to be on.

Adamek’s promoter, Kathy Duva, said Friday morning that her fighter and Klitschko “seem to have ironed out our differences” for one of the best-possible heavyweight matchups in September.

“I think we’re there,” she said as she was reviewing what she called the final draft of a contract. “We still have cross our Ts and dot our Is, though.”

Thus, Adamek will not fight Sam Peter in a title-elimination bout, as had been discussed.

Instead, he’ll take a less-challenging tune-up bout in April. One possibility reported by numerous sources is 38-year-old former heavyweight champion Hasim Rahman, who was 4-0 last year against journeymen after returning from more than a year away from boxing.

Klitschko, who holds two heavyweight belts, is scheduled to face journeyman Dereck Chisora on April 30.
