San Jose Sharks defensemen Marc-Edouard Vlasic, who sustained a lower-body injury in a 4-3 win against the Carolina Hurricanes on Saturday, and David Schlemko, who has missed three games with a leg injury, each declared themselves ready to play Tuesday, but coach Peter DeBoer said each would be a game-time decision. The Sharks have won seven of their past 10, and have allowed 19 goals in that span. "I don't know if a coach is ever pleased all the way defensively, but we've come a long way," DeBoer said. "We started the season a little loose, we weren't scoring, and we kind of reset and tried to dial our defensive game in a little bit. We tried to get a 1-0, 2-1 type mindset and I think that's paid off for us." Center Joe Thornton's line, with forwards Patrick Marleau and Joe Pavelski, are expected to go up against the Toronto Maple Leafs line of Leo Komarov, Nazem Kadri and Connor Brown. "I think faceoffs are a huge part of it, whoever you are playing against, if you start without the puck, it's going to be a lot harder," said Thornton, who has five assists in his past four games but has not scored a goal in his past 15. Goaltender Martin Jones is expected to start.
