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.
Hancock's spokeswoman, Amber Miller, initially says the mayor 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 double-overtime home loss to the Ravens on Saturday.
