The on-again/off-again matchup between heavyweight champion Wladimir Klitschko and David Haye is back on again.

According to Golden Boy CEO Richard Schaefer via Doug Fischer of Ring Magazine, contracts have been exchanged and the details are being sorted, but the fight will take place on June 20 in Europe.

A specific location has not been agreed to, but that was the holdup for some time. The fight was close to done at other times, but has always hit breaking points. Originally, Haye was promising big crowds in London, but was unable to make the fight happen where he wanted to for economic reasons. Then, he offered to fight in Germany, but the holdup then came from other reasons and talks broke off.

Recently, Haye was apparently pushing for the fight to happen in the United States, but eventually all parties agreed to fight in Europe at a yet to be determined site.

According to Shaefer, Germany may still be the frontrunner for the fight, but nothing is for sure right now.

HBO will televise the fight.
