I don't think Gagner can go regardless of being a pro. Doesn't the AHL have a 19 (20?) age limit?
I'm not clear with what the exact rule is, but I think if your junior team's season is over, you can go play. Ryan O'Marra is an example of that, he played in the AHL for the playoffs and a couple of games at the end of the year as an 18 year old.
Unless your CHL team is eliminated, which London is. JFJ played in the AHL as a 19 year old, O'Marra did as an 18 year old.
I found this:
"Europeans and NCAA Players can play in the AHL at 18
CHL players must have 4 yrs under their belt in the CHL if they don't they must wait until they turn 20 European CHL players can be assigned to the AHL by their NHL teams to the AHL before age 20 example Petr Kalus"
I also found this post from last year:
"There is a private agreement in place between the NHL and the CHL that governs when a player coming from the CHL can play in the AHL. A player from the CHL has to either turn 20 by December 31st of the season (ie a player born in 1987 can start playing in the 2007-08 season, a player born in 1988 can start playing in the 2008-09 season etc.) OR have completed 4 seasons of junior eligibility. This agreement also covers European players if they are drafted out of the CHL (Examples would be players like Petr Vrana and Ivan Vishnevskiy). Also - CHL players are eligible to play in the AHL once their junior season is over (either by virtue of their junior team not making the playoffs or being eliminated from the playoffs) even if they don't yet meet the age or eligibility criteria listed above."
So the only reason JFJ was allowed to play (at that age) was because he put in 4 years in the CHL. So they are allowed play at 18 /19 only for the playoffs apparently.
I still would not send Sammy down. Let the kid rest. He has some serious weight training regimes to put on a bit of muscle I am sure during the Summer.
Also - CHL players are eligible to play in the AHL once their junior season is over (either by virtue of their junior team not making the playoffs or being eliminated from the playoffs) even if they don't yet meet the age or eligibility criteria listed above."
That says that he can play, however maybe it would be best for him to get some time off. But the kid is still only 18, I don't want to hear anything about "burn-out"
IMO sending Cogliano and Nilsson down would be enough to help the team, so if Gagner wants time off, let the kid rest.
