UPDATE: Maclin returned to the game and is apparently fine.
Chiefs WR Jeremy Maclin ran a slant and was lit up hard by a Chargers defender who seemed to go straight to the head of Maclin. The video seemed to show to me that the Chargers defender led with his helmet and hit Maclin in the helmet, which should be a penalty. There was no flag. The CBS announcers couldn't believe there was no flag on there for what looked like an illegal hit.
Hate to see shots like this hit on Jeremy Maclin. https://t.co/OJLOcbWstY

Fox's Mike Pereira thought it should've been a flag.
To me, the hit on #Maclin should have been a foul.. there was contact to the head/neck area and he was a defenseless receiver #KCvsSD

Maclin remained down for a few minutes and walked off with Chiefs trainers. He already has one concussion this year and the Chiefs are currently evaluating Maclin for this hit.
Maclin really looked wobbly coming off field after yet another helmet shot by Chargers, uncalled. He's getting the once-over on sideline.

Good God that hit on Maclin. Just brutal.

How did the refs miss that helmet-to-helmet hit? It's bad enough we don't know what is a catch, but that hit is pretty cut and dry.

If that isn't a flag for leading with the crown, nothing is.

Shots to Thomas, Kelce (twice), and now Maclin heads. The Chargers' game plan seems obvious.

That's an illegal hit. Maclin is a tough guy, but you can't do that. He's should get a fine for that one.
