Toronto FC was at it again on Thursday.

The Reds made yet another trade, sending defender Dan Gargan and a second round pick in the 2012 MLS SuperDraft to the Chicago Fire for defender Dasan Robinson.

Robinson, 27, has appeared in 82 games for Chicago during his career, scoring three goals. This season he has played in five matches for the Fire, two as a starter.

"We had an opportunity to acquire another defender and provide depth for our club," coach Aron Winter said in a press release. "I'd like to thank Dan for his contributions to our club but we felt this was a move we needed to make. Dasan brings us depth and versatility because he can play central defence or right

A source told CBCSports.ca that TFC originally released Gargan earlier this week but then rescinded the move and traded him to Chicago after the Fire expressed interest in the defender.

Gargan's departure comes on the heels of some major moves by the Reds.

Earlier this month, Winter made three separate trades — including one that shipped Nana Attakora, Jacob Peterson and Alan Gordon to the San Jose Earthquakes — and signed free agent defender Eddy Viator.

In late June, the club added two designated players: German midfielder Torsten Frings and Dutch forward Danny Koevermans.

Gargan, a 28-year-old native of Philadelphia, joined TFC at the start of the 2010 MLS season.

A fourth-round pick (43rd overall) of Colorado in the 2005 draft, Gargan was cut by the Rapids in 2008 and went on to announce his retirement. It turned out to be a short sabbatical, as he joined the Puerto Rico Islanders of the USL First Division in 2009, before landing in Toronto the following year.

He established himself as a regular starter during his first season with the Reds, and he scored his first career MLS goal during a 1-1 draw with the Houston Dynamo on July 1, 2010. This season, he played in 16 games (12 as a starter) and accumulated 1,063 minutes in playing time.

He leaves TFC having played in 43 MLS games.

With a 3-11-9 record and 18 points, Toronto currently sits in last place in the Eastern Conference, and is eight points out of a playoff spot with 11 games remaining in the regular season.

Toronto later announced it had signed Perica Marosevic, a 22-year-old former FC Dallas forward.

Marosevic, a Bosnian-born American, has no goals in just four MLS games since Dallas drafted him fifth overall in the 2009 MLS SuperDraft.
