HOUSTON — Deshaun Watson threw for 210 yards and two touchdowns and ran for a third as the Houston Texans set a franchise record with their eighth straight win, 34-17, over the Tennessee Titans on Monday night.

Demaryius Thomas scored his first two touchdowns as a Texan, and Lamar Miller rushed for 162 yards, including a 97-yard scoring run.

In the first game since founder and owner Robert McNair died on Friday, the Texans (8-3) honored him by wearing decals on the back of their helmets in the shape of a football with white block letters bearing his initials, R.C.M.

With that reminder on their helmets, they became the first team in N.F.L. history to win eight games in a row after starting 0-3. They lead Indianapolis by two games in the A.F.C. South.
