On the day the Earthquakes acquired central defender Bobby Burling from Chivas USA, the biggest development involved club star Darren Huckerby.

The English left wing is getting his troublesome hip examined in Colorado, a team spokesman said Friday. No further details were released.

The team''s best player last season, Huckerby has missed a handful of matches this year because of a thigh injury. He said in June that he also needed to resolve a hip problem in the offseason.

The 6-foot-5 Burling, who has played for Chivas for three years, underwent ankle surgery in the offseason and hernia surgery in March. He has played in three matches in 2009. The Quakes sent a third-round draft pick to Chivas in a move that signals the end of Fabio da Silva''s brief tenure. The team had to sign da Silva, from Brazil, to bring him to San Jose as a trialist.

But coach Frank Yallop has been satisfied with the recent play of central defenders Jason Hernandez and Brandon McDonald.

Also, Aaron Pitchkolan, who suffered a left-groin injury in July, is about to return.

"They ain''t coming out any time soon," Yallop said of Hernandez and McDonald. "It will take a while to break into those two."
