United States women’s national team star forward Alex Morgan sustained a mild medial collateral ligament (MCL) sprain in her left knee that led to her being stretchered off during Portland Thorns FC’s 2-1 loss to the Boston Breakers on Wednesday, the Thorns announced today.

She is expected to miss between two and four weeks of action, but there should be no lasting damage from the awkward landing. Immediately after leaving the game in the eighth minute, Morgan was taken to an on-site trainer’s area for examination before going to the locker room and emerging with a stabilizing knee brace on her left leg.

“It’s a relief that there is no significant damage to my knee,” Morgan said in a club release. “I will do everything in my power between now and Aug. 24 in order to be available for the playoffs and to win the championship.”

With her team’s spot in the final four assured, Morgan can afford to miss Portland’s final National Women’s Soccer League regular season game on Aug. 17, when it travels to play Seattle Reign FC.

The U.S.’s next scheduled match is a friendly against Mexico on Sept. 3 at RFK Stadium in Washington, just three days after the NWSL final will be played and nearly four weeks from last night, the date of Morgan’s injury.
