The Pittsburgh Post Gazette has reported that Sidney Crosby left practice at West Point early on Monday due to soreness in his groin. While the severity of his current injury is unknown, a groin pull can be can be a very debilitating and longer term injury for a hockey player. Sidney Crosby previously experienced a groin injury during the 2006-07 season. The injury sidelined him for a total of three games in late November. Crosby is reported as saying his current pain is less than that which he experienced in November 2006. He is hopeful he can still take part in the West Point team-building exercises and maneuvers, however, an abundance of caution would suggest that he be rested until all signs of the injury are gone.
