There’s a good chance Dan Boyle will enjoy the Olympic break more than any of his teammates. Returning from a serious head injury suffered in October isn’t the only health issue the 37-year-old defenseman has been dealing with, according to a team source, as Boyle suffered a thumb injury in the Sharks’ 3-0 loss in Edmonton on Jan. 29. He played through it in the Sharks' final five games before the break, including Friday against Columbus. Boyle has admitted in recent weeks he probably came back too soon from getting checked headfirst into the boards by Maxim Lapierre in St. Louis on Oct. 15, as he tried to play through a series of symptoms such as lack of sleep and no appetite. He missed just seven games, returning on Nov. 2, despite being knocked unconscious for several minutes and stretchered off the ice at Scottrade Center. Boyle should be fine to play in the Sharks’ first game after the Olympic break, on Feb. 27 in Philadelphia. The Sharks’ non-Olympians will resume practice on Feb. 19.
