Earthquakes forward Steven Lenhart is expected to miss at least four weeks with a sprained medial collateral ligament in his left knee, the club announced Thursday.
Lenhart, who has not scored in three MLS matches this season while logging 258 minutes, went down in the 77th minute of a 2-1 loss to the New England Revolution on Saturday.
"We'll miss him, but as always with injuries it gives guys an opportunity," coach Mark Watson said. "Alan Gordon, who has been working his way back to fitness, is pretty close. Billy Schuler, Adam Jahn, all the other guys that have been working hard and waiting patiently."
Lenhart also had arthroscopic surgery on the meniscus of his right knee in 2011 and 2012. He scored four goals in 2013 after posting a career-high 10 in 2012.
The Quakes (0-2-1), after a bye this weekend, will play host to the Columbus Crew (3-0) on April 13 at Buck Shaw Stadium.
Stanford senior Felicia Lee was named the Honda Sports Award winner as women's college swimmer of the year. Lee, who led Stanford to a runner-up finish at the NCAA championships last month, is now a finalist for the Collegiate Woman Athlete of the Year and the 2014 Honda Cup.
The other swimming finalists were teammate and Pac-12 performer of the year Maya DiRado and Olympians Missy Franklin of Cal, Breeja Larson of Texas A&M and Brittany MacLean of Georgia.
Lee won the 100-yard butterfly and helped four Stanford relay teams place first at the NCAA championships. "It's important to recognize that it's not really just an award for me; it's for my coaches, my teammates, my parents, and everyone who has helped me along the way to get here," Lee said in a statement.
The series leaves SJSU with one more nonconference opening for both the 2015 and 2016 seasons. A previously scheduled 2016 game with Colorado will no longer be played.
