Fight is on HBO tonight.

Fight is at Madison Square Garden in NYC.

Klitschko (49-3, 44 KOs) holds the IBF & IBO titles. Ibragimov (22-0-1) holds the the WBO belt.

This will be the first heavyweight unification bout since Lennox Lewis / Evander Holyfield in 1999.

My prediction: Klitschko has a good jab, is a STRONG puncher and the taller fighter. Ibragimov is a southpaw with good defensive skills that may take Klitschko a few rounds to figure out. Klitschko wins in a later round TKO (probably the 9th or 10th).
