The Sharks decided that eight defensemen in San Jose were one too many Sunday and sent Nick Petrecki to their Worcester development team for conditioning. The move is considered a loan, and therefore Petrecki did not have to go through waivers, where he could have been claimed by another team. The Sharks lost left wing Frazer McLaren last week when he was picked up by the Toronto Maple Leafs. Petrecki, whose only action came in the Jan. 29 game against Anaheim, also stays on the 23-man roster and continues to earn his NHL salary. With Jason Demers healthy and Matt Irwin -- for one game at least -- moved into the seventh slot as insurance, Petrecki wasn't likely to see action at the NHL level. Demers' ice time in his first game back was 18:48, and he was credited with four hits, one blocked shot and one take-away. He said he felt good about his first game back after recovering from a wrist injury suffered in Europe. "They say the first period you kind of feel tired, but in the second I felt good and in the third I had my legs and all that," Demers said. "The battle part of it, when you start pushing guys, you can't re-create that in practice. That kind of plays into fatigue, but I felt good."
