With the franchise tag contract negotiation deadline looming at 2 p.m. MDT, Thomas and the Broncos signed a five-year deal.
"Demaryius is a special talent and an elite player who has also become a team leader during his five NFL seasons. We are very much looking forward to him playing a major role in the success of the Broncos well into the future."
Thomas will enter his sixth NFL season coming off his best year as a pro to date after he set single-season and single-game franchise records in receiving yards in 2014 with 1,619 and 226 yards, respectively. With at least 1,400 receiving yards and 10 receiving touchdowns in each of the past three seasons, Thomas joins the elite company of Jerry Rice and Marvin Harrison.
Thomas also had seven consecutive 100-yard receiving games, which was a Broncos record and one game short of tying the NFL record. His 10 total 100-yard receiving games in 2014 was also a franchise record and one short of tying the NFL mark.
The Broncos drafted Thomas in 2010 with the 22nd overall pick in the first round. He finished his collegiate career with the fourth-best mark in receiving yards (2,339) and in touchdown catches (15) in Georgia Tech history.
