Race officials allowed both runners into Friday’s final, but D’Agostino won’t be there. She was carted off the track in a wheelchair and an exam later showed she has torn her right ACL and strained her MCL.

In a statement Wednesday, she said she had known all along that her trip to Rio de Janerio was going to be more about her race performance, and as soon as Hamblin got up after the fall, her purpose for being in Brazil was clear.
