So sorry to read this news, kind of buried in this article:
As the large invitational meet buzzed all around her, Oregon's premier high school track and field athlete, Mia Brahe-Pedersen of Lake Oswego, said that the leg injury that knocked her out of the indoor season in January was re-aggravated the day before she was set to compete at the Pepsi Florida Relays. She suffered a muscle tear that has forced her to end her high school track career and shift her attention to college at USC in the fall.
Clearly this also means the end of her Olympic hopes until 2028 as well. :(
