Texans free safety Andre Hal had plenty of opportunities to tag Indianapolis Colts wide receiver T.Y. Hilton and make sure he was down.
Instead, though, Hal didn't even try to touch him because he was convinced the play was over.
The result was an 80-yard touchdown pass as Hilton, who had jumped over Texans cornerback Kareem Jackson earlier on the play, got up and raced into the end zone.
"Yeah, I thought he was down," Hal said. "I thought they had got him down. I can't make no assumptions. I got to make sure he's down.
