Tennessee was driving the field, trailing the Texans 14-7 in the fourth quarter when Ryan Tannehill passed to Kalif Raymond for a short pass on second down.
Instead, Scarlett was flagged for unnecessary roughness, which set the Titans up with first-and-goal from the Texans' seven-yard line.
"Yeah, I got a good look at it," the head coach said with a smirk.
The questionable call did not hurt the Texans in the long run, but it could have.
"That’s tough, because especially looking at the replay on the big board, I clearly hit the guy with my shoulder," Scarlett said after the game. "It wasn’t near the head or neck area. It’s tough on the other side, it’s a bang-bang play. The refs, that’s what they see, and I just wish it would’ve been a reviewable call, especially at that point in the game in a critical situation. So, I’m disappointed in that."
