The Texans needed a clutch play as Indianapolis Colts quarterback Andrew Luck was threatening to extend his advantage in the first half.
They got the impact play they needed from an unlikely contributor.
Just promoted from the practice squad this week, reserve cornerback Robert Nelson intercepted Luck at the Texans' eight-yard line.
It was a huge play from the former Arizona State cornerback.
Nelson has previous stints with the Arizona Cardinals and Cleveland Browns.
It was the first career interception for Nelson, appearing in his eighth game of his NFL career.
