Titans LT Mike Roos vs. Falcons DE John Abraham: Roos has made 105 consecutive starts and is a tenacious battler. He was voted first-team All-Pro in 2008 and second-team in 2009. Abraham, who's in the last year of his contract, had two sacks in the opener and only one over the next eight games. The Falcons hope he can step it up down the stretch.

Titans RB Chris Johnson vs. Falcons MLB Curtis Lofton: Johnson rushed for 130 yards and had 174 yards total in a 30-3 victory over Carolina on Sunday. After a slow start, Johnson's chance of adding to his string of three consecutive seasons of at least 1,200 yards rushing is in jeopardy. Lofton ranks third in the NFL with 85 tackles, according to nfl.com. He has 100 tackles according to the coaches' film-review stats. Lofton is the key figure in the Falcons' run defense, which ranks third in the league, and has had double-digit tackles in seven games this season.

Titans WR Damian Williams vs. Falcons CB Dunta Robinson: Williams, a former second-round pick from USC, had a breakout game Sunday. He caught five passes for 147 yards and a touchdown. The Titans hope that he's starting to fill the void left by the season-ending knee injury to Kenny Britt. Robinson was part of a five-player missed assignment against the Saints on Sunday. He doesn't have an interception this season, as the Falcons have relied on a lot of zone coverages.
