To call Saturday’s boxing main event big is an understatement. Anthony Joshua (18-0; 18 KO) vs. Wladimir Klitschko (64-4; 53 KO) is the kind of fight we should be seeing more of in boxing - a true clash between the top dogs. This is a Heavyweight title fight for the WBA, IBO, and IBF titles. Ring Magazine has it as a battle between the division’s #1 contender (Klitschko) and #5 (Joshua). The fight will air live on Showtime this Saturday, April 29 with a fight time of 4:15 p.m. ET and will be replayed on HBO that night at 11:00 p.
