The Denver Broncos have ruled out two key defensive players for their opener against the Tennessee Titans on Sunday: inside linebacker Dre Greenlaw and defensive tackle Malcolm Roach. Greenlaw has been bothered by a left quadriceps injury all offseason. After pulling up lame in a one-on-one drill July 31, he was held out of the Broncos’ three preseason games and both of their joint practices in training camp.
