SI.com has learned fight is close to being finalized

A unification fight between IBF heavyweight champion Wladimir Klitschko and WBO champion Sultan Ibragimov is close to being finalized, Klitschko's manager Bernd Boente told SI.com on Friday.

We are still waiting on the last signatures from Ibragimov`s people," said Boente in an email. "Hopefully we can get it done -- we all would love the unification." The fight would take place on February 23rd at Madison Square Garden.

Considered by many as the best of the current heavyweights, Klitschko is at the top of the independent IBO rankings. Ibragimov won by unanimous decision against Evander Holyfield last month.
