The Vitali Klitschko-Kevin Johnson heavyweight bout will be part of HBO's boxing broadcast that includes the Juan Diaz-Paul Malignaggi rematch on Dec. 12.

The special duel-site triple header will kick off with the Diaz-Malignaggi co-feature, Victor Ortiz vs. Antonio Diaz, and then air the main event rematch from the UIC Pavilion in Chicago before showing Klitschko-Johnson from the PostFinance Arena in Bern, Switzerland, tape delayed.

American fringe contender Johnson (22-0-1, 9 knockouts) is the third opponent for Klitschko (38-2, 37 KOs) this year. Klitschko's last fight, a 10th-round stoppage of undefeated Chris Arreola on Sept. 26, was HBO's highest-rated boxing program of the year so far.
