HOUSTON -- Dallas Cowboys quarterback Tony Romo has opted to retire, NFL Network Insider Ian Rapoport reported Tuesday morning.

Adam Schefter with ESPN says Romo is leaving football and going into broadcasting. Schefter reports Dallas is planning to release Romo today.

Last week, Texas head coach Bill O'Brien went to the AFC coaches breakfast with a stock response when asked if there was a future for Romo in Houston.

"I've had no conversations with the Cowboys," the Houston Texans coach said.

For weeks, speculation pegged Houston as the likely landing spot for Romo.

And not much from O'Brien about the prospect of adding Romo to his mix.

"I’m a coach. I don’t have any trade discussions with anybody, and like you said, he’s under contract with the Cowboys and that’s really all I can say about that," O'Brien said. "I’m not going to get into speculation of whether he’s released, what we (would do). Like I said, and I really mean it, we’re really looking forward to working with the guys that we know are going to be there on April 17th, at every position."
