From the Caps:
"A total of 68 players will be on the ice at Kettler Capitals Iceplex in the upcoming weeks for the 2007 Washington Capitals rookie camp and training camp, vice president and general manager George McPhee announced today.
"Thirty rookies will participate in rookie camp, which begins this Saturday, Sept. 8, and runs through Wednesday, Sept. 12, when the rookies travel to Philadelphia to scrimmage the Flyers’ rookies.
"Training camp begins Friday, Sept. 14 when 38 veterans – 24 of whom saw action for the Capitals last season – will join selected rookies to get ready for the upcoming 2007-08 NHL season.
