The National Women's Soccer League says it is looking at its protocols surrounding player safety following the collapse of Angel City defender Savy King during a match in Los Angeles.

The NWSL Players Association has demanded that the league update its policy on game postponements in the wake of a medical event during Angel City's win over the Utah Royals on Friday, with defender Savy King later undergoing surgery to correct a heart abnormality.

Angel City FC defender Savy King underwent successful surgery Tuesday, following her on-field collapse during a match on Friday, the team said.
