LONDON - Unbeaten Deontay Wilder will have a ringside view of rival heavyweight champions Anthony Joshua and Wladimir Klitschko in their unification showdown at Wembley Stadium on Saturday, with hopes to fight the winner by December.

The 31-year-old American, who owns the World Boxing Council crown, will serve as a television analyst when Britain's unbeaten Joshua (18-0, 18 KO) defends his International Boxing Federation crown and vies for the vacant World Boxing Association title against Ukraine's Klitschko (64-4, 53 KO), before a sellout crowd of more than 90,000.

"I'm excited to see it," said Wilder, who owns a record of 38-0, with 37 knockouts.
