IBO cruiserweight champion Antonio Tarver (29-6, 20KOs) is ready for some big challenges in 2012. The 43-year-old veteran has a wish list for 2012, which includes either a unification with WBC champion Krysztof Wlodarczyk or a title defense against WBA-interim king Denis Lebedev of Russia. Beyond those two, Tarver would love to return to the heavyweight division to fight former WBA champion David Haye, who retired in October. Or even better, Tarver wants WBO/IBO/WBA/IBF champion Wladimir Klitschko.

"My wish list for 2012, Lebedev or Krysztof Wlodarczyk first, David Haye in Madison Square Garden, and Wladimir Klitschko in any part of the world," said Tarver.

One fighter who wants piece of Tarver is British heavyweight Audley Harrison. Tarver's interest lies with Audley's countryman, Haye.

"[Haye is] more relavent at this time in the heavyweight division. I get more out of knocking out Haye than Audley," Tarver said.
