With Detroit already trailing by 11 points nearly halfway into the 3rd quarter, the Texans were at midfield. Brock Osweiler threw a pass to DeAndre Hopkins, who appeared to come down with both feet, start to turn, and have the ball knocked out.
The play was blown dead and called incomplete. Jim Caldwell did not challenge.
It looked like a play that could have been overturned to a fumble, though with replay nothing is certain. However, given the score situation, how low did the chances need to be to risk a challenge? Coaches struggle with challenges in low leverage situations and deciding when to optimize. A potential turnover at midfield is pretty high leverage.
Houston went on to get a field goal on this possession to go up 17-3, and Detroit has now pulled within one touchdown in the fourth quarter.
