You can add the Indianapolis Colts to this list. I just picked up a 2008 Dante Hughes game used home jersey from their team website.

They have about 20 different player jerseys for sale and they range from $250-$1000. They also have game used footballs and a limited number of helmets available. All items come with a team COA.
