The Indiana Fever have been very unlucky with injuries this season, and it seemed like Kelsey Mitchell had joined the list. Mitchell appeared to go down with a non-contact leg injury in the third quarter of Game 5 on Tuesday. She was tended to by the Fever's training staff and was taken back to the locker.With around five minutes into the second half, Mitchell drove to the basket after getting a screen from Aliyah Boston, who was called for a moving screen. The lefty scorer then began to limp after the call was made and just went down to the floor with a problem on her left leg.The medical team, her teammates and even the Las Vegas Aces players expressed concern for Mitchell. They surrounded her and even blocked the cameras with towels as a stretcher was called to assist.According to ESPN's Alexa Philippou, Kelsey Mitchell was helped to the back, and the stretcher wasn't used. However, she was ruled out for the rest of the game and is now being re-evaluated.Alexa Philippou @alexaphilippouLINKIndiana Fever guard Kelsey Mitchell has been ruled out for the remainder of the game, per the Fever.
