ENGLEWOOD, Colo. (AP) — Pat Surtain II is out and Dre Greenlaw in back. Denver's defense saw some shuffling this week as the Broncos (6-2) prepared to put their five-game winning streak on the line Sunday at Houston, where the Texans (3-4) were installed as slight favorites. Surtain, the NFL's reigning Defensive Player of the Year, is expected to miss multiple games with a strained left pectoral muscle he injured while making a tackle last week in Denver's 44-24 rout of the Dallas Cowboys.
