Forward Alex Morgan suffered a slight MCL injury, the Portland Thorns announced today, following examination by Thorns Director of Medicine, Dr. Richard Edelson.

Morgan is expected to miss between two and four weeks, and will begin rehabilitation immediately at Providence Sports Care Center at JELD-WEN Field in Portland Oregon.

Morgan suffered the injury in the 8th minute of their match Wednesday at Boston, when she and Breakers’ defender Jazmyne Avant collided while challenging for the ball. Morgan was down for several minutes before being stretchered off the pitch by medical personnel, but came out to the Thorns’ bench at halftime.

“It’s a relief that there is no significant damage to my knee,” Morgan said in a press 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,”

The Thorns lost the match against the Breakers, 2-1, but still clinched a spot in the 2013 NWSL Playoffs following Chicago’s 1-0 defeat to Washington.

The Thorns conclude the regular season away at Western New York on August 10 and at Seattle on August 17. With playoff seeding yet to be determined and 3 of the four teams sitting at 34 points, Morgan is a significant loss for a Thorns side seeking hosting rights for the playoffs.
