So it appears that Hickey had to be put on waivers and was not claimed when he was put "on loan" to Manchester back in September.
ahhhhhh....nope:
"There’s also a chance that more players could be headed to Manchester during a (probable) NHL lockout. There are five additional players who meet the criteria to sign an AHL-only contract during the lockout. They are Andrew Campbell, Marc-Andre Cliche, Rich Clune, Thomas Hickey and Jake Muzzin. So, there is a way for the Kings to get those players to the AHL without the waiver process, but there’s no guarantee that they will sign those AHL contracts. We should know more in the next few days."
