Kia Nurse has suffered a torn ACL and will be out for the remainder of the season, the Phoenix Mercury announced Friday.

Nurse went down with the injury at 39 seconds into Game 4 of the WNBA Semifinals. The Las Vegas Aces went on to win that game 93-76 and force a Game 5 for a trip to the WNBA Finals.

Sophie Cunningham, who has a calf strain, has been listed as questionable.

Nurse is a big loss for the Mercury, as the third-year guard played in every game and averaged 9.5 points, 3.5 rebounds and shot 35.3 percent from three-point range in her first season with Phoenix.
