(AP) — Andrew Luck threw a 7-yard touchdown pass to Jack Doyle with 1:55 left to put Indianapolis ahead to stay, and the Colts rallied to beat the Tennessee Titans 34-26 Sunday for their 10th straight win against their AFC South rival. Colts kicker Adam Vinatieri kicked a pair of field goals, and the second, a 33-yarder with 3:46 left in the third quarter gave him an NFL record 43 consecutive field goals made. The Colts pounced on the Titans with an onside kick after Luck's second TD with 10:16 left in the second quarter. The Colts had to settle for a 28-yard field goal by Vinatieri after having first-and-goal, but the onside kick helped the Colts go up 17-6 with 10 straight points. [...] cornerback Perrish Cox went down late in the same quarter when linebacker Sean Spence appeared to land on him, and Cox was carted to the locker room where he was evaluated for a concussion.
