Tobin Heath will miss the remainder of the NWSL season after undergoing surgery on her left knee Monday.

OL Reign announced Friday that Heath has been placed on the season-ending injury list, with her recovery timeline expected to extend beyond the 2022 campaign.

“Although this wasn’t an easy decision, we know this was the right decision,” OL Reign coach Laura Harvey said. “We always want to be mindful of our athletes and their health, so we wanted to be sure that Tobin will have the proper time needed to fully prepare for a successful return on the pitch. Despite missing time this season, Tobin has helped our younger players tremendously with her veteran mindset and experience.”

Heath had missed the last two OL Reign matches. She posted a photo and message to her Instagram on Tuesday after her surgery. “No one said it would be easy,” her caption read.

A mainstay for the U.S. women’s national team through the 2021 Olympics in Tokyo, Heath received an outpouring of support from fellow stars, including USWNT teammates Ashlyn Harris, Rose Lavelle and Sofia Huerta.

Since joining OL Reign in June, Health has appeared in five games with the club, notching one goal.
