DENVER -- Denver Mayor Michael Hancock insists he is not trying to renege on a bet after he injured his leg at a stock show.

Hancock lost a bet with Baltimore mayor Stephanie Rawlings-Blake that requires him to perform linebacker Ray Lewis' signature pre-game dance after the Denver Broncos lost to the Ravens.

The mayor's spokeswoman, Amber Miller, initially said Hancock suffered an unspecified injury during "pre-game" warm-ups on Monday to pay off the wager, but later said he pulled a muscle and will fulfill his promise after he heals.

The top-seeded Broncos were eliminated from the playoffs in a 38-35 home loss Saturday to the Ravens.
