NFL Star Jay Cutler UNLOADS Mansion In Colorado

Jay Cutler has cut even more ties in Colorado -- the former Denver Broncos quarterback finally sold off the mansion he lived before he was traded to Chicago ... TMZ has learned.

According to official documents, Cutler purchased the home in Parker, CO in 2005 for $1.34 million. Cutler put his home up for sale in 2010 for $1.625 ... but nobody took the bait.

Cutler eventually lowered his asking price ... and the 5,344 square foot estate finally sold on July 19 for a cool $1,000,000.
