Report: Cowboys to release Romo on Thursday

The Dallas Cowboys will release longtime quarterback Tony Romo on Thursday, sources told ESPN's Adam Schefter and Todd Archer.

The move would end his 14-year tenure with the only pro team he's ever known, after he landed in Dallas as an undrafted free agent out of Eastern Illinois. He became the team's franchise quarterback in 2006.

Despite his strong individual play for the better part of a decade, Dallas only played six playoff games with Romo as starter.

He registered one of his best seasons as a pro in 2014, but succumbed to a back injury that was followed by a collarbone fracture and another back injury in the next two years. The back injury he suffered last preseason opened the door for rookie quarterback Dak Prescott to take the reins of the Cowboys' offense.

Rendered a backup, Romo was slated to make $19 million in 2017 and count at $24.7 million against the cap if he remained a Cowboy.

Romo is likely to be designated a post-June 1 release, which would allow the Cowboys to spread out his cap hit over two years, as Spotrac notes.

The 36-year-old owns a shaky injury history, but is expected to command a lot of attention on the free-agent market in a year loaded with teams in need of a starting quarterback.

The Denver Broncos have often been mentioned as a suitor. The club signed the last big-name quarterback to hit the open market, Peyton Manning, in 2012 in order to make a run at the Super Bowl.
