Washington Mystics starting guard Tayler Hill will miss the rest of the season after tearing the anterior cruciate ligament in her right knee during the third quarter of a win over the Indiana Fever on Friday.

Hill, the Mystics’ second-leading scorer, left the court in a wheelchair after landing awkwardly while coming down from a layup. She was writhing in pain under the basket and had to be carried off the floor.

For a team still working out the kinks that came along with a completely retooled roster, losing Hill could be a big setback for Washington. The guard averaged 13.3 points per game in 25.6 minutes per night and was a dependable floor general, dishing an average 2.6 assists per game.

Star forward Elena Delle Donne was also injured in Friday’s game against Indiana — which the Mystics won, 72-58, to halt a three-game losing streak. Delle Donne sprained her right ankle and missed Sunday’s game at the New York Liberty, which the Mystics lost, 85-55.
