Veteran guard Courtney Vandersloot left midway in the first quarter of the Chicago Sky's game against the Indiana Fever on Saturday at the United Center.
Vandersloot attacked the basket and was fouled by Fever's Aari McDonald. The 15-year WNBA veteran hit the deck and immediately grabbed her right leg. She was helped to the locker room following the play.
Elizabeth Williams, who subbed in for Vandesloot, went 1-for-2 from the free-throw line. The Fever had a 9-7 lead at that point.
Moments later, the Sky announced that the veteran guard won't return to Saturday's game due to a knee injury.
Vandersloot is her second stint with Chicago after returning this offseason. In her two seasons away from the Sky, the veteran helped the New York Liberty reach back-to-back WNBA Finals, eventually winning it all last season.
Courtney Vandersloot reacts to being the Sky's all-time leading scorer
Courtney Vandersloot had a historic night during the Chicago Sky's 97-92 home win over the Dallas Wings on May 29. She surpassed her wife, Allie Quigley, to become the Sky's all-time scoring leader. Quigley held the record with 3,723 points.
During the postgame press conference, Vandersloot was asked what the feat meant to her.
"Well, first, for what it means to me, the most is just my time spent here," Vandersloot said (Timestamp: 05:48). "Obviously, it took me a thousand years. But you know, I think it just speaks to like the commitment that I made to the Chicago Sky and their commitment to me as well.
"You know, they drafted me and let me come and develop. And it wasn't always easy, we had a lot of tough seasons, and so that means the most to me."
Courtney Vandersloot is also the Sky's all-time leader in games played (364), assists (2,424) and steals (468).
Chicago selected Vandersloot with the No. 3 pick of the 2011 WNBA draft. She spent 12 years in her first stint with the Sky. In six games this season, the five-time All-Star is averaging 12.0 points, 6.2 assists and 3.7 rebounds on 43.1% shooting.
