The Earthquakes suffered a late-season blow Monday when learning newly acquired midfielder Mehdi Ballouchy will be lost for the year after tearing the anterior cruciate ligament in his left knee. Ballouchy, 29, will undergo surgery this week, a team spokesman said.
The right-side midfielder suffered the injury Saturday night against FC Dallas when awkwardly kicking at a ball in the 51st minute. He landed hard on the field, tearing the ligament.
"The news was very disappointing," Earthquakes coach Frank Yallop said in a statement. "Mehdi was just settling in with our squad and was playing very well for us."
Ballouchy was brought in to boost the midfield flanks for a playoff run.
Starting winger Marvin Chavez is sidelined with a left hamstring muscle strain and left-side midfielder Simon Dawkins is nursing an ankle sprain. Another speedy wing, Shea Salinas, returned last weekend for the first time in six games because of a hamstring strain.
Ballouchy was the MLS's second overall draft pick in 2006 out of Santa Clara. The 5-foot-11 Moroccan who attended Palo Alto-Gunn High started the past four games for the Earthquakes and had six appearances overall.
Stanford's men's golf team bettered Sunday's performance by 12 strokes and is tied for seventh after the second round of the Olympia Fields (Ill.)/Fighting Illini Invitational.
