Posted by ESPN.com’s Bill Williamson

DENVER -- The Broncos and Steelers have traded defensive touchdowns.

Denver took a 10-7 lead when rookie linebacker Robert Ayers picked up a Ben Roethlisberger fumble and ran 54 yards for a touchdown with 11:16 to go in the third quarter. Denver defensive lineman Kenny Peterson caused the fumble on a sack. Ayers was a first-round pick acquired in the Jay Cutler trade with Chicago.

In the first half, Pittsburgh scored on an interception return following one of the few mistakes Denver has made all game.
