Knowshon Moreno does obstacle course crawl to signal first down (GIF)

Knowshon Moreno's game at Arrowhead Stadium Sunday started with a bizarre moment when he shed the biggest tear drops known to mankind (bottom GIF) during the national anthem.

Later, the Bronco running back's less strange, but still intense behavior would continue. After going 31 yards —half of it with a pile of Chiefs players on his back — Moreno found himself on the ground under a scrum of scuffling players from either side. And he signaled a first down in the only way possible — like a grunt crawling under barbed wire on an obstacle course.

All and all, an interesting day for the former New Jersey high school star.

Peyton Manning fooled Cowboys defense AND Broncos offense on rushing touchdown (GIF)

While everyone on the Dallas Cowboys defense piled on Knowshon Moreno on this second quarter play, Peyton Manning faked out everyone by moseying in for his first rushing touchdown in five years. And even his own Broncos teammates didn't know Manning had planned to scamper left for the score.

After the game, the Denver Broncos tweeted that Manning didn't even tell his own team that he was going to take it in himself on this third-and-goal jaunt so his offense would sell the running back up-the-middle play better.

Manning said he was the only one that knew he'd keep the ball on his TD run so that everyone else would sell the RB run better.

Manning already had three TD passes in the first half and — after his unmolested run faked out everyone from the cameraman to his own team — the Broncos quarterback even did a little fist pump as he crossed the goal line.

Omaha!
