Tennessee Titans (1-2) at Indianapolis Colts (1-2)

Sunday, 1 p.m. ET, at Lucas Oil Stadium, Indianapolis — TV: CBS

*TV announcers: Kevin Harlan, Rich Gannon

*Keys to the game: It’s not a full-blown revival but the positive signs and strong commitment to RB Trent Richardson is making life a little bit easier for QB Andrew Luck behind an offensive line still coming together. Luck leads the NFL with nine touchdown passes and will see seams in Ray Horton’s 3-4 defense to attack. He has been sacked five times, and most of the Titans’ pressure comes from the interior defensive line, where Tennessee sees likable matchups. DT Jurrell Casey had two sacks in the last meeting.

The Titans’ ability to attack Indianapolis downfield depends on QB Jake Locker’s status. He was out midweek with a wrist injury with Charlie Whitehurst, a game manager, has not thrown a pass in a regular-season game since 2011. The Titans are in a major funk, scoring just 17 points total in the past two games. If Locker can’t go, the Titans will lean on their running game and hope that the likes of Shonn Greene and Bishop Sankey can run effectively and keep the ball out of Andrew Luck’s hands as much as possible.

*Matchup to watch — Titans NT Sammie Hill vs. Colts C A.Q. Shipley: Shipley has done such a good job filling in for Khaled Holmes that the Colts are sticking with him. Hill needs to be strong at the point of attack on the inside to help the Titans stop the run and get pressure on Andrew Luck.

*Player spotlight — Colts WR Donte Moncrief: A third-round pick in May, Moncrief has caught six passes through the first three games for 80 yards. He saw extensive playing time over the final two quarters of last week’s win at Jacksonville and could play a major role if T.Y. Hilton (ankle) sits.

*Fast facts: The Cots have won five consecutive meetings. … Tennessee has not scored in the first quarter this season.

WHO WILL WIN AND WHY

The Colts are becoming more balanced and that’s bad news for opponents like the Titans, who don’t have the firepower to keep pace.

*Our pick: Colts 32-21
