I believe Jones WILL have to clear waivers in order to return to Manchester. Please correct if I'm wrong. He is no longer on his ELC. Remember he was a little bit of a hold out this off-season. Finally singing a few days after training camp started.

Claiming goalies on waivers is a little tricky since you have to keep him on your NHL roster for 30 days. So, essentially a team would have to chose Jones over one of their current goalies. With the way Jones is playing and the reputation of being a goaltending factory that the Kings are starting to get. Putting him on waivers is gonna be risky!
Also to keep in mind is Jones has 1 year left on his contract after this season. While Scrivens will be an UFA. So, we could lose Jones on waivers and lose Scrivens to free agency.... Which would really suck!
If I'm correct in that Jones does have to clear waivers. I wouldn't be shocked in Scrivens is traded in a couple weeks when Quick is back. Which is crazy considering all he's done. But, Jones in my opinion is the safer player to go with.
If Jones keep this play up. It's gonna be interesting to see what Lombardi does!
