The Texans won their fourth straight regular season opener and picked up their first franchise victory against the San Diego Chargers, improving to 1–4 against them on the late game of ESPN's Week 1 Monday Night Football doubleheader.

In a hard-fought defensive battle, Tennessee built up a lead as big as 24–16 before Houston sent it to overtime behind Arian Foster's TD run and 2-point conversion with 1:53 to go in regulation.

But with a 20–6 fourth quarter lead, Houston gave up two touchdowns, including a pick-six by Richard Sherman to tie the game at 20.

At halftime, head coach Gary Kubiak collapsed on the field on his way to the locker room with a Transient Ischemic Attack.
