What happened: Boone Jenner scored the tiebreaking goal past backup Dylan Garand late in the second period on Friday night. Timothy Liljegren and Tom Wilson added insurance tallies for Washington, while Alexis Lafreniere provided New York's lone goal. The matchup turned when Igor Shesterkin was helped off the ice midway through the frame.

Why it matters: The goaltender jammed his right skate into the post and collapsed in pain, requiring assistance to leave the surface without putting weight on his leg. This raises immediate concerns for the Rangers, who finished last in the Eastern Conference last season when he missed a month with a lower-body issue. Jenner's decisive goal resulted directly from a defensive zone turnover by rookie Cole Beaudoin, who was acquired last summer in a trade for Vincent Trocheck.

What to watch: The Rangers host the Vancouver Canucks on Sunday. The Capitals host the Seattle Kraken the same day.
