Goalkeeper Jon Conway, suspended last year by MLS for 10 games for taking performance enhancing substances, was signed Friday by Chivas USA, the club announced Friday.

In addition, defender Bobby Burling, a Loyola Marymount University product who has played just three games this season because of injury was shipped to the San Jose Earthquakes, who badly need to shore up their defense.

The same could be said for Chivas USA’s goalkeeping situation, where back-up Lance Parker has shipped goals at a prodigious rate while filling in for the injured Zach Thornton.

Conway, 32, is a nine-year MLS veteran; the Red Bulls – who had retained his MLS rights despite terminating his contract in June – received a fourth-round 2011 MLS SuperDraft pick in return. Conway, who trained with the Chivas USA for several weeks this season, is eligible to play Sunday against FC Dallas.

Chivas USA received a third-round draft pick next year for the 24-year-old Burling.

Conway and defender Jeff Parke had tested positive for androstatriendione (ATD) and boldenone metabolites – performance enhancing substances banned by MLS.
