JACKSONVILLE, Fla. -- Tim Tebow's attempted NFL comeback has officially begun.

The 2007 Heisman Trophy-winning quarterback signed his contract with the Jacksonville Jaguars on Thursday as a tight end, reuniting him with Urban Meyer, his former head coach at Florida.

Tebow signed a one-year deal and was on the field Thursday for the team's offseason program as he sets out to compete for a roster spot. Tebow joined his new team on the field wearing No. 85 -- quarterback Gardner Minshew has No. 15 for now -- and took part in a voluntary, closed workout.

"I want to thank the Jaguars for the opportunity to compete and earn the chance to be part of this team," Tebow said in a statement. "I know it will be a challenge, but it is a challenge I embrace. I am dedicated to taking the direction of our coaching staff and learning from my teammates. I appreciate everyone's support as I embark on this new journey."

Tebow, who will turn 34 in August, hasn't played football since the 2015 NFL preseason and has spent the past six years working as a broadcaster on the SEC Network and working on his professional baseball career. He was adamant about being a quarterback during his previous six-year stretch in the NFL with the Broncos, Jets, Patriots, and Eagles, but he apparently has had a change of heart now that Meyer is running the Jaguars.
