Sources tell Adam Schefter and me the Dallas Cowboys will release Tony Romo on Thursday, the first day of the league year. Romo will leave the Cowboys as the franchise leader in passing yards and touchdowns after a 14-year run with the team, including 10 years as the starter. Denver and Houston are expected to be among the teams interested in Romo, who turns 37 in April. What is not known is whether the Cowboys will outright release him or designate him as a post-June 1 cut.
