The Chelsea player grabbed her right calf in the 64th minute after making a pass, then sat down on the grass, Aftonbladet reports. It was Björn's first minutes on the pitch since a thigh injury kept her out of action.
Chelsea, with Johanna Rytting Kaneryd in the starting eleven, won the final 2–0. United started with the Swedish trio Ellen Wangerheim, Julia Zigiotti Olme and Hanna Lundkvist, while Fridolina Rolfö was substituted.
Sweden's next international match will be the World Cup qualifier against Denmark on April 14.
