Steelers vs. Broncos
Ryan Mundy vs. Tim Tebow/Eric Decker/Demaryius Thomas
The Broncos' 31st-ranked air attack won't be favored to do much against the Steelers' league-best pass defense, but they did catch a slight break earlier this week when Pittsburgh head coach Mike Tomlin announced that starting free safety Ryan Clark is out for Sunday. Clark, the Steelers' leading tackler, will be held out due to a sickle-cell trait that becomes aggravated when playing at higher elevations. Tebow (15), Decker and Thomas will look to exploit Clark's replacement, Ryan Mundy (29), a fourth-year player who will be making just his third career start.
