Late in the game Sunday against the San Francisco 49ers, momentum was changing. The Lions had cut the 30-13 deficit to 30-27, and the defense was facing a third-and-2 with 2:23 left in the fourth quarter. The scene had all the makings of another signature Matthew Stafford comeback.
Niners quarterback Jimmy Garoppolo dropped back to pass and threw a pass left, only to be picked off by rookie safety Tracy Walker and returned deep into San Francisco territory. A late flag negated the play and gave San Francisco an automatic first down, with Quandre Diggs called for a hold on tight end George Kittle.
