Tony Romo has been released by the Dallas Cowboys, allowing him to end his NFL career and join CBS as a broadcaster.
Romo, who was displaced by Dak Prescott as the Cowboys starting quarterback last season after suffering a back injury in preseason, had been talked up as a target for a number of teams including the Denver Broncos and Houston Texans.
But he will instead move into the commentary booth, replacing Phil Simms as an analyst working alongside Jim Nantz on the network's top NFL broadcast team.
Romo's 14-year career with the Cowboys saw him set franchise records for career passing yards (34,183) and touchdowns (248). He also owns the fourth-best career passer rating in NFL history (97.1).
"When you think about the NFL, two of the most iconic brands are the Dallas Cowboys and CBS Sports," Romo said in a statement. "Going from one legendary team to another as I begin the next phase of my career is a dream come true.
"I have always known that once my playing career was over I wanted to become a broadcaster. I am ecstatic for the opportunity to work with Jim as I learn the craft and convey to fans my passion for this great game."
The 36-year-old Romo reportedly walked away from the NFL primarily because of health concerns following two injury-hit seasons.
"We wish Tony and his family nothing but the best," Cowboys owner Jerry Jones said in a release. "As an organisation, we did what he asked us to do in terms of his release, and we wanted to do what was ultimately in his best interest and in the best interest of his family.
"Tony has been a wonderful representative of the Cowboys organisation for 14 years, and he left everything he had on the field. He will leave us with many great memories and a legacy of being, truly, one of the greatest players in Cowboys history. We are thrilled for him and his family that he will be able to continue working as a professional in the game he so dearly loves."
Head coach Jason Garrett added: "That relentless spirit that Tony plays with is contagious. He makes his team-mates better. He makes his coaches better. He makes his team better. He has grown so much as a player and as a person over the course of his career and has made a significant impact on the lives of so many.
"I consider myself fortunate to be at the top of that list. It has been one of the great privileges of my life to work with Tony Romo, one of the greatest players in Dallas Cowboys history."
