No 4 Auburn 2021, entire game
This game is one where the Hogs truly fought the refs, as well as their opponent. Only one year after the Bo Nix backward pass debacle, Arkansas caused a fumble deep into Auburn territory. The replay officials in Birmingham felt differently about the situation, saying the ball carrier's forward momentum stopped. Therefore, the play was dead.
The problem is the whistle wasn't blown until Jarquesz Hunter was already on the ground, which happened after the ball came loose. You can even see an official throw a bag, indicating a fumble.
But that wasn't all. Two invisible pass interference calls extended Auburn drives. The last one against Hudson Clark was the most infuriating. Not only was there no contact except the normal hand fighting, the ball was 10-15 yards out of bounds. The Tigers went up by double digits shortly after the call.
