Chivas USA has been busy lately as the club traded defender James Riley to D.C. United, while also signing defenders Steve Purdy and Carlos Borja.

Riley leaves the Goats for United in exchange for a second-round pick in the 2015 MLS Supplemental Draft.

The 30-year-old is a veteran of eight MLS seasons and he made 32 starts for Chivas last season.

Purdy, 28, spent the last two campaigns with the Portland Timbers, while the 25-year-old Borja moves to Chivas after spending last term with USL side Los Angeles Blues.

The club also declined to pick up the contract options of Paolo Cardozo, Ryan Smith and John Valencia, while waiving Cesar Romero.
