TAMPA — The Lightning's approach to Game 5 of the Eastern Conference final will not be altered no matter who starts in goal tonight for the Penguins."We can't worry too much about what they do with their goalie," C Alex Kil lorn said Saturday. "It doesn't change anything we do."Penguins coach Mike Sullivan pulled Matt Murray after the rookie allowed four goals during the first two periods of the Lightning's 4-3 win in Game 4 on Friday. Marc-Andre Fleury , who had not played in the postseason after suffering a concussion in March, played the third period and made seven saves to keep the Penguins in the game as they rallied with three goals.Sullivan said Saturday that his decision about who starts Game 5 would come today."Marc's been a big part of this team all year," he said. "He's really helped this team get to the position it's at with the way he's played all season. The timing of his injury down the stretch was unfortunate. It's not a perfect circumstance. But I think that's the nature of the business we're in. We just try to make the best decisions and make the most of the situation that we're in."Fleury, the Penguins' goalie since 2008, led them to the 2009 Stanley Cup championship. Murray helped the Penguins knock off the Rangers and Capitals in the first two rounds and had the Penguins up 2-1 in this series heading into Game 4."(Fleury has) been their franchise goalie for a number of years, and I don't think it really changes anything because ultimately they're playing a guy (Murray) that was on fire," Lightning coach Jon Cooper said. "He's carried them to this point. I think whatever decision they make, you still got to put the puck behind them." Daley update: D Trevor Daley , second on the Penguins in ice time (22:08) this postseason, could be lost for the rest of the series after leaving Friday's game with a lower-body injury. He was seen leaving Amalie Arena on Friday on crutches with his left foot in a cast. Sullivan said Daley would be re-examined once the team returned to Pittsburgh."He's a leader out there on the ice," Pittsburgh D Brian Dumoulin said. "He's definitely an important person we want on the ice." That's hockey: Almost lost in Game 4's frantic finish was a three-minute stretch in the second period that produced a four-minute power play for the Lightning and led to LW Jonathan Drouin 's goal and a 3-0 lead.Penguins D Kris Letang was whistled for a cross-check on Drouin and then got into it with C Brian Boyle and received an additional two minutes for roughing, as did Boyle, who reached around Dumoulin to continue to his altercation with Letang."I have no excuse," Letang said. "I should be on the ice. I should be more disciplined. I (messed) up."Boyle said he wasn't trying to get the Penguins' best defenseman in the penalty box. That's just how it worked out. "Things like that are going to happen. If players on one side are going to do something, the other team answers, and that's kind of how it's always been," Boyle said. "It's just how it goes. A little pushing and shoving, and then play hockey." NUTS AND BOLTS: Forwards Joel Vermin and Tanner Richard were signed to one-year, two way deals. No details were available.
