Dallas Cowboys QB Tony Romo (clavicle) has ‘a lot of football left in him,’ according to head coach Jason Garrett. ‘We do think (the collarbone) is an injury that will heal,’ Garrett said. ‘We do think the back injury has gotten better and better over time. He’s more able to handle the work day-to-day and the work week-to-week, so I think that’s improved. We do think the collarbone will heal. He’s got a lot of football ahead of him.’
