Nazem Kadri scored an unsassisted goal 3:56 into overtime to lead the Calgary Flames to a 3-2 win over the Boston Bruins on Thursday night. Kadri took the puck up ice on a 3-on-1 and fired a shot into the far corner past Linus Ullmark just seconds after Jakob Markstrom stopped David Pastrnak at the other end. “I was exhausted by the end of that one, just an absolute track meet,” Kadri said.
