The Chicago Sun-Times reported Friday the eight-year veteran wants a new deal.
"I never said that I was going to quit," Urlacher told the Chicago Tribune. "Reports like that are why I choose not to speak to the media."
He has four years left on his existing contract, which will pay him $57 million.
The report added that an unnamed league source said Urlacher's agents have asked the team if they could explore a trade and that he is threatening to retire because of neck and back problems.
He is not participating in voluntary off-season workouts and is threatening to be a hold out at mini-camp in May.
In 2007, he failed to make the Pro Bowl for the first time despite a team-high 158 tackles and being the NFL's first player ever with five sacks and five interceptions in the same season.
