It's 50/50 at this point.
If anywhere, it'll probly foul up at the poppet. If that does happen you could bleed off the pressure, pull the post, and remove the poppet without having to disturb the beer in the keg. Re-pressurize and dispense as usual. Just remember and mark the keg that you pulled the poppet or you might get a foam jet on the ceiling when you go to swap it out.
Regardless, I'd wait til it plugs to do anything.
