Following a loss to the Winnipeg Jets that prompted Phil Housley to call for his team to show a greater sense of defensive urgency, the Buffalo Sabres held a physical, competitive practice at KeyBank Center on Wednesday morning. With that physicality came emotion, and potentially a loss on defense. Zach Bogosian had to be helped off the ice while battling Evander Kane for a loose puck in the corner on one drill. On another, emotions boiled over and prompted an exchange between Kane and Justin Falk. Housley said that the team will know more regarding Bogosian's status once he's finished being evaluated later in the day. As for the confrontation between Kane and Falk, all sides agreed that the emotions shown may have been healthy for a struggling team. "It was just spur of the moment," Falk said. "Emotions are running high this time of year, where we're at … To be honest, maybe a little bit more stuff like that is probably what we need to get things going here, to get guys playing with a little more passion and urgency." "It's good to see some emotion," Housley added. "It was a battle practice out there, focusing on some areas that we need to improve on, and tempers flared up. It was more about just being in the heat of the battle and guys being frustrated at where we are. Sometimes emotions get high." Buffalo's 7-4 loss to Winnipeg on Tuesday was its fifth in a row, and Housley attributed the ongoing struggles afterward to a "lack of respect and urgency" on the defensive side of the puck. Jason Pominville, who's been on playoff teams in nine of his 12 full NHL seasons, agreed.
