Melvin Ingram sacked Trevor Siemian in the second quarter of the Chargers’ matchup with the Broncos. He was flagged for roughing the passer, even though it was a clean hit.

Ingram comes up the middle totally unblocked. He hits Siemian in the chest and pulls him to the ground.

The Chargers have a top-five pass rush this season, with 18 sacks so far. But Ingram’s didn’t count because of the penalty.
