The Premier League side have announced striker's exit from the club after two-and-a-half year, and has now joined the MLS outfit alongside fellow Frenchman Mikael Silvestre
West Ham have confirmed the termination of Frederic Piquionne's contract by mutual consent following the striker's switch to MLS side Portland Timbers.
The 34-year-old joined the Hammers from Lyon for a fee of £1 million in July 2010, going on to score 11 goals in 62 games during one-and-a-half seasons in the first team.
However, Piquionne has failed to make a single appearance this campaign after joining Doncaster Rovers on loan for the second half of last term, and has now opted to join Portland Timbers - where he will be joined by fellow Frenchman Mikael Silvestre.
"I am delighted to sign for Portland," Piquionne told reporters. "It is a one-year contract. Mikael Silvestre is here with me, so settling in will not be as difficult as I think.
"We will try to do very well, as much as we can for Portland. For me, it will be another great experience to play in another great league."
Aside from Lyon and West Ham, Piquionne has enjoyed spells with the likes of Saint-Etienne, Monaco and Portsmouth during a professional career spanning 13 years.
