Broncos DT Marcus Thomas is out for the rest of the preseason due to a strained pectoral muscle. The Broncos probably feel like they dodged a bullet after fellow defensive tackle Ty Warren was diagnosed with a torn triceps. Thomas, who had just passed Kevin Vickerson for a starting gig, has a chance to be ready for Week 1. Still, the moves the Broncos made to fortify the gut of their defense have been nullified. After giving up an unruly 154.6 yards per game on the ground last year, the Broncos figure to struggle against the run again.
