Jaguars tight end Geoff Swaim left Sunday’s ugly loss to the Saints after being knocked out cold by a brutal helmet-to-helmet hit.  New Orleans linebacker Demario Davis was flagged for the illegal hit.

Swaim, who went completely limp after the brutal shot to the head, eventually was able to get up to begin treatment for what was an obvious head injury.
