Seattle Sounders FC goalkeeper Stefan Frei took an accidental knee to the head with seconds remaining in stoppage time and was taken off the field in an ambulance during his team's 1-1 draw with the Columbus Crew on Sunday.

Frei jumped forward to make a play on a free kick, and as he came down, his head collided with the knee of a Crew player. Frei dropped to the turf at Lumen Field and teammates signaled to the sideline for help.

Seattle coach Brian Schmetzer and the Crew's Wilfried Nancy agreed to call the game with Columbus due for a corner kick.

As Frei was stretchered to the waiting ambulance, Seattle fans chanted his first name.

Frei, 39, has played for the Sounders since 2014. He helped Seattle win the MLS Cup in 2016 and 2019, and he was named MLS Cup MVP in 2016. He was an All-Star in 2017.
