Deontay Wilder says a grueling training camp has honed his “killer” instinct as he prepares to put his World Boxing Council heavyweight crown on the line against Britain’s Tyson Fury next month.

Wilder, who is unbeaten in 40 fights with 39 knockouts, faces off against the undefeated Fury at the Staples Centre in Los Angeles on December 1 in what is set to be an explosive encounter.

The 33-year-old Wilder, who is eyeing a potential future bout with IBF, WBA and WBO heavyweight champion Anthony Joshua next year, told reporters in Los Angeles on Monday he was in prime condition after his training camp.

Wilder’s last outing was a bruising battle with Cuba’s Luis Ortiz in March. Wilder won that contest with a 10th round technical knockout after being forced to dig deep by the Cuban. Wilder said Tuesday he had benefited by being given a rough ride against Ortiz.

Wilder meanwhile said he is confident his raw punching power will be able to overwhelm Fury’s awkward but orthodox style.

Wilder’s trainer Jay Deas revealed that the camp had used smaller but more mobile sparring partners to help Wilder prepare for the athletic challenge posed by Fury.
