There’s rarely a must-win game in Week 6, but the Tennessee Titans needed a victory on Monday night to keep pace in the AFC South. Thanks to a big pass by Marcus Mariota and a breakaway run by Derrick Henry, the Titans emerged from a tussle with the Indianapolis Colts with a share of the division lead. Mariota hit Taywan Taylor with a 53-yard touchdown pass with 5:29 to play and Henry’s 72-yard touchdown run with 47 seconds left helped the Titans seal a 36-22 victory over the Colts, snapping Tennessee’s 11-game losing streak to its division rivals and evening the team’s record at 3-3.Mariota was a game-time decision to play after missing the team’s last game with a hamstring injury, but it didn’t seem to affect his throwing.
