Toronto FC traded Brazilian midfielder Paulo Nagamura to Chivas USA Friday.
In return, Toronto receives Chivas' first-round pick in the 2008 Major League Soccer draft.
"We're sad to see Nagamura go, but he wanted to go, and now he's headed back to Los Angeles," Toronto coach Mo Johnston said in a statement.
Nagamura was picked up by Toronto from the Los Angeles Galaxy at last November's expansion draft.
The defensive midfielder started all four of Toronto FC's games this season, playing a total of 354 minutes.
On Wednesday, Toronto had come to terms with Chivas on a deal for Honduran star Amado Guevara in exchange for Nagamura and a first-round pick in next year's draft.
But the deal fell through the next day when Guevara balked at being sent to Toronto and Chivas ended up releasing the temperamental midfielder, who is set to return to Honduras.
With Guevara off the table, Toronto reworked the trade with Chivas where it would receive a first-round draft pick in exchange for Nagamura.
Johnston told CBC Sports Online Friday morning the trade hit a snag on Chivas' end and that Nagamura could be staying in Toronto, but the two sides came to terms and the deal was completed in the afternoon.
Veteran midfielder Ronnie O'Brien, who missed the first four games of the season with a knee injury, looked sharp in Friday morning's practice. Johnston said he will be available to play against Chicago May 12, Toronto's next contest.
"I'm feeling a little bit better. The knee is starting to feel pretty good," O'Brien told CBC Sports Online.
O'Brien continues to practise with a brace on the troubled knee and said he'll likely have to keep wearing it a few more weeks, but is optimistic he'll be back at 100 per cent soon.
"It's got a lot better through this week. I took a day off and it got so much better from doing it. I'm not feeling it too much any more.This brace is ungodly looking, but it's doing its job," said the Irishman.
