A worthy response.
I would guess that this isn't anything more than the Chiefs keeping a punter on tabs in case something does happen to Dustin Colquitt. As far as I know, he's fine right now.
There was a scare earlier this season in Week 4 when a New York Giants player ran into him and he hit the deck. While that was a scare, he did finish that game. He was listed on the injury report after that with a knee sprain. But he's been playing since then.
So I'm guessing that the Chiefs are just keeping an eye on free agent punters in case something does happen.
