In an interview with 1053 The Fan, Jones said that he's "not sure anyone knows" how long the quarterback will be out.
Romo left after three snaps in Thursday's preseason game against the Seattle Seahawks. It was later announced that he suffered a broken bone in his back.
Jerry Jones on @1053thefan talking Tony Romo return timetable: "I just don't know." Said it could be 4-6, 6-8 or 8-10. Not sure anyone knows— Jon Machota (@jonmachota) August 30, 2016
For now, rookie Dak Prescott looks poised to steer the ship. Prescott has had the best preseason of any quarterback.
One area where Cowboys and Tony Romo dodged a bullet -- No ligament damage in Romo's back, I'm told. Should be training again in 3-6 weeks.— Albert Breer (@AlbertBreer) August 29, 2016
Romo, 36, will not require surgery but will need adequate time to heal. The Cowboys have a week 7 bye week and some analysts expect him to eye a week 8 return. Jones also said that the team is deciding if they want to put Romo on injured reserve. That move would have him sit out for at least the first eight weeks of the 2016 season.
My understanding is that best-case scenario is that #Cowboys QB Tony Romo returns by mid-season. He broke a different bone than last time.— Ian Rapoport (@RapSheet) August 27, 2016
Romo hasn't played a 16-game season since 2012. Last season he missed 12 games after a collarbone injury. He has broken his collarbone three times.
Monday Morning Quarterback's Albert Breer reported Monday that Romo "should be training in 3 to 6 weeks."
