ST. LOUIS -- Joe Thornton and the San Jose Sharks won the matchup of unbeaten teams. But the Sharks had more pressing concerns for teammate Dan Boyle. Thornton had a goal and three assists and Patrick Marleau had a goal and two assists and the Sharks downed the St. Louis Blues 6-2 Tuesday night. Boyle was lost for the game with a head injury suffered early in the first period. Boyle was taken off on a stretcher early in the first period following a check from behind by the Blues Maxim Lapierre, who was ejected from the game for checking from behind. A Sharks spokesperson said Boyle was alert and responsive on the way to the hospital. Boyle will be kept overnight for observation. Thornton was one of the first players on the ice. "He wasnt (saying anything) and thats what was so scary," Thornton said. "Ive never seen a guy be like that before. It just takes your breath away. He wasnt responding or anything. It was very, very scary." Several Sharks players were critical of Lapierre afterward. "Its just disgusting to see that type of play in hockey, when a player that probably shouldnt even be in this league is taking out one of the best players in the world," said Sharks centre Logan Couture, who had a goal and an assist. "(Lapierre) has got a history." Added Joe Pavelski, who scored his first goal of the season: "Idiots are idiots out there. Dan is a world-class defenceman ... (Lapierre saw) straight numbers (in front of him). Theres guys in the league that will target that ... It doesnt matter, theyll just go. It (stinks). Guys responded appropriately." Sharks coach Todd McLellan gave the good news of Boyles status. "Well, he left and he went to the hospital and from what I understand, hes doing OK," McLellan said. "A very scary moment, needless. It doesnt have to happen in our game. It doesnt have to happen." Blues captain David Backes also expressed his concern afterward. "No one in their right mind would ever want that to happen to another guy," Backes said. "Our thoughts and prayers are with Dan Boyle and his family. Thats a scary thing, its something you hope never happens. Hopefully he has a speedy recovery and hes back on the ice soon. "Nobody ever wants that to happen. Its a tough thing to see that and to put it behind you and keep playing. Thats disturbing." Tommy Wingels and Scott Hannan also scored, while Antti Niemi stopped 25 shots for San Jose (6-0-0). The Blues, who dropped to 4-1-0 on the season, had their 10-game regular-season home winning streak snapped as the Sharks won in dominating fashion. Jaroslav Halak also suffered his first defeat of the season, stopping 22 shots and was replaced by Brian Elliott to start the third period. It was Elliotts first action of the season. Vladimir Tarasenko broke Niemis shutout with his fourth goal in as many games for the Blues. Roman Polak also scored for the Blues. "Its tough because its Dan Boyle and theres so much respect in this office because of history with Dan," Blues coach Ken Hitchcock said. "I havent really looked at it that closely on the video to be honest with you, so I dont want to comment on it until I looked at it a few times," Hitchcock added. "I dont think that had anything to do with the outcome today. One team played hard and smart." After the Boyle injury, it was a penalty-filled first period, with 79 minutes in penalties handed out. Lapierre was ejected for a five-minute checking from behind penalty as well as fighting, as was teammate Ryan Reaves. The Sharks also lost forward and Matt Pelech with a fighting major and game misconduct. Andrew Desjardins was originally awarded a fighting major and 10-minute game misconduct, but was changed to a 10-minute misconduct and he was able to return for the second period. Later in the period, San Joses Brent Burns checked the Blues Brenden Morrow from behind into the boards, but only got a two-minute boarding penalty to the resounding boos from Blues fans. The Sharks took a 2-0 lead on power-play scores from Couture and Pavelski just 48 seconds apart. Both goals came from the left circle, with Couture scoring at 9:37. The Blues trailed on home ice for the first time since April 16, 2013, a stretch of 568:47. Pavelski one-timed his first of the season on the short side past Halak just after a 27-second two-man advantage for the Sharks expired. The Sharks added to their lead in the second period, getting goals from Wingels and Hannan to grab a 4-0 lead. Wingels scored on a wraparound off the skate of Barret Jackman 8:34 into the period for a 3-0 lead, and Hannan with his first of the season off a slap shot with 2:47 left in the period for a 4-0 lead. Thornton made it 5-0 on a shot from the slot, beating Elliott 5:06 into the third period off a pass from rookie Tomas Hertl. Tarasenko hammered home a rebound off a shot from Jaden Schwartz at 7:23 of the third period to make it a 5-1 Sharks lead. Polaks shot from the low slot with 7:32 remaining cut the Sharks lead to 5-2. Marleau added his fifth of the season at 17:06, the Sharks third power-play goal of the game and put a stamp on a game they dedicated to their teammate. "Your heart kind of drops," Thornton said. "Its tough seeing a teammate go down like that. We had to give a good effort for Dan tonight. Ive never seen that before, youre just kind of sitting on the bench hoping Dan is OK. It takes a while to kind of get back focused again." NOTES: Hertl leads the NHL in rookie scoring with nine points. ... San Joses win was only its second in the past eight meetings with the Blues. ... The Blues previous home regulation home loss was April 14, 2013, to Chicago. ... The Sharks lead the NHL in goals (30) and goal differential (plus-21). ... Polaks goal was his first since April 11, 2013, second in two seasons and 10th of his career. Mats Hummels Jersey .
