BRANDON — In case you have ever wondered how much power Lightning D Mikhail Sergachev packs into his slap shot, he provided an answer in the form of shattered glass on Wednesday.In between drills during practice, Sergachev fired a puck toward the net from the blue line. He didn't make it into the net. Instead, the puck cut right through the glass panel behind the net, prompting glass to come crashing down onto the ice.Curious how much power a Mikhail Sergachev slap shot has? Here’s your answer pic.twitter.com/HFWDIPiCvo— Nick Kelly (@_NickKelly) October 10, 2018A cleanup crew quickly took care of the glass on the ice and outside of the rink while practice continued.Braydon Coburn deserving of shootout opportunity? In its first game of the season, the Lightning had an early opportunity to try a couple of players out in a shootout.The Lightning rolled out forwards J.T. Miller, Nikita Kucherov and Brayden Point. Miller and Kucherov got the job done, but maybe D Braydon Coburn gets consideration down the line.At the end of practice Wednesday, Coburn scored shootout goals against goaltenders Andrei Vasilevskiy and Louis Domingue. Teammates did everything from cheer for him to sprawl out on the ice in an effort to celebrate after Coburn surprised with scores against each goaltender.Coburn probably won't be called on early in a shootout anytime soon, though. Still, kudos to the defenseman for showing a handful of fans at the Ice Sports Forum what he can do with the puck.Practice lines ahead of game vs. VancouverOndrej Palat – Steven Stamkos – Nikita KucherovYanni Gourde- Brayden Point – Tyler JohnsonAlex Killorn – Anthony Cirelli – Mathieu JosephAdam Erne – Cedric Paquette – J.T. MillerCory Conacher – Danick Martel – Ryan Callahan• Conacher and Martel likely will be healthy scratches Thursday if these lines are any indication and Johnson returns. Callahan continues to nurse a shoulder injury. He continues to be full contact, though. The five-month recovery process after shoulder surgery would put his expected return to game action in early November.• Paquette was a full participant in practice Wednesday. He did not participate fully Monday after suffering a hand injury in the Florida game. He had also missed some of the game after another player skated over his glove during a faceoff.• The only line that remains intact from the first game is the third line. Said Lighting coach Jon Cooper: "We are just trying to find chemistry a little bit."
