The United States cruised into the semifinals at the women's world hockey championships but may have lost one of its most important players to injury.
Forward Abbey Murphy left a 14-0 win over Denmark in the first period with a lower-body injury after a collision in the neutral zone.
There was no update on Murphy's status after the game.
Murphy has three goals and five points in five games at the tournament. The University of Minnesota alum was the No. 2 pick in the PWHL Draft and will begin her rookie season with the Seattle Torrent next month.
The Americans will face Finland in the semifinals on Saturday, while Team Canada will play Sweden in the other semifinal.
