During the first quarter of the Houston Texans and Baltimore Ravens game, officials failed to call an obvious pass interference despite a challenge flag being thrown.
Deshaun Watson attempted a deep pass to DeAndre Hopkins, who was wrapped up by cornerback Marlon Humphrey. Hopkins was tackled before the ball arrived in the end zone.
Texans head coach Bill O'Brien challenged for defensive pass interference, but official Al Riveron announced that the non-call on the field stands.
Houston would have had the ball on the one-yard line.
The first quarter ended with both teams scoreless.
