Reigning WNBA MVP Breanna Stewart is expected to miss the upcoming season after she ruptured the Achilles tendon in her right ankle.

Stewart, 24, injured the leg on Sunday in the EuroLeague Women's championship game in Hungary. She flew to Los Angeles where test results confirmed the injury.

The Seattle Storm announced the diagnosis Wednesday. Stewart won both the league and finals MVP awards while leading the Storm to the franchise's third WNBA title in 2018.

"As we all know there are highs and lows throughout a career," Stewart wrote on Twitter. "This is just another obstacle that I will overcome."

Stewart was playing for Dynamo Kursk, a Russian club, when the former UConn star appeared to land awkwardly on the foot of fellow WNBA star Brittney Griner after attempting a jumper late in the first half against UMMC Ekaterinburg. She immediately grabbed at her lower right leg while grimacing in obvious pain.

"This is a tough time for Stewie and our hearts go out to her," Storm CEO and General Manager Alisha Valavanis said.

The WNBA season begins May 24.
