The NFL acknowledged Tuesday that officials failed to call the Dallas Cowboys for a holding penalty against Detroit Lions defensive lineman Ndamukong Suh on a fourth-down conversion pass from Tony Romo to Jason Witten in the fourth quarter of Sunday’s NFC wild-card game in Arlington, Texas.

If the penalty had been called, the Cowboys would have faced a fourth-and-16 and likely opted to punt. Instead, they picked up the first down at the Lions’ 21-yard line and drove to the winning touchdown with 2:32 left.

That play happened after the controversial interference call that was waived off on a pass to Detroit’s Brandon Pettigrew. NFL head of officials Dean Blandino said Monday that that the non-call on the interference ruling against Cowboys linebacker Anthony Hitchens was subject to debate but that there was no doubt about the hold on Suh.

Lions quarterback Matthew Stafford questioned during the game the flag being picked up on the pass to Pettigrew.

“Can we explain that or no?” Stafford, who was wearing a microphone during the game, apparently asked officials. “Just flat-out overturning a pass interference call?”
