[MLS] Two weeks after trading Brandon McDonald to D.C. United for allocation money, San Jose sent money, an international player slot, and forward/midfielder Ryan Johnson to Toronto FC in exchange for three players.

Forward Alan Gordon, defender Nana Attakora and midfielder Jacob Peterson are headed west in the deal, which TFC conducted in part to acquire an international slot to accommodate the acquisitions of German midfielder Torsten Frings and Dutch striker Danny Koevermanns.

They can be officially added to the roster when the secondary transfer window opens Friday.

Gordon, 29,  played for Quakes coach Frank Yallop with the Galaxy in 2006 and 2007. In eight seasons with three teams, he's scored 21 goals in 116 league appearances. The Galaxy traded him last season to Chivas USA, which sent him to Toronto last March in exchange for midfielder Nick LaBrocca. He has four goals in eight games this season.

Attakora -- like Yallop a citizen of Canada -- joined TFC during its expansion season of 2007 and played 56 times. He has represented Canada at the U-17 and U-20 levels and debuted for the senior team in 2010. He has played centerback and outside back in MLS.

Peterson, 25, began his MLS career in 2006 with Colorado after playing for Indiana's NCAA Division I championship team in 2004. He played for the U.S. U-17 and U-20 teams before starting his pro career. He's scored nine goals and recorded six assists in 129 league games.

Johnson, who was born in Jamaica and raised in the Boston area, had brief stints with Real Salt Lake and Chicago in 2006 before playing for a season in Sweden and returning to MLS in 2008.

He played left midfield and forward for the Quakes, which he led in goals with 11 in 2009. In 99 league matches for San Jose he scored 17 goals and contributed 13 assists.
