I don't have a complete list of 'Cats that are attending their respective development camps but I'll tell you what I've found - all players' stat page at hockeydb.com can be linked to through the roster further down the page.
Kevin Regan - Bruins' Prospect Camp, Ristuccia Arena, Wilmington Mass. - they'll be running camp through Saturday where you can see action at 1:30 Friday and 2:00 Saturday.
Mike Radja and Phil DeSimone (pictured here at the Capital Fanatic blog
) - Capitals' Development Camp, Kettler Capitals Iceplex, Arlington Va - the schedule is here
, you can see Radja was a late addition to the roster.
James van Riemsdyk - Flyers' Mini-Camp
- and you can read what the Director of Player Development had to say
Brian Foster - was reportedly
at Panthers' Camp from June 3rd-10th which is verified here
although I could not find a synopsis of the action from their camp.
Joe Charlebois and Peter LeBlanc - were listed as attendees
of the Chicago Blackhawks development camp although I was unable to find a synopsis of their presence either.
Craig Switzer - got a nice write-up
from New England Hockey Journal on his experience at Predators' Prospect Camp.
Not sure if he attended a camp but Brad Flaishans deserves even more recognition for his academic accomplishments which were well noted
on the Texas Tornado site.
