Portland Timbers forward Eddie Johnson announced his retirement on Friday, bringing an end to his 10-year professional career.

The 27-year-old signed with the Timbers in 2010 and scored one goal in seven matches for the club in its inaugural MLS season.

His time has been limited by injuries, however and he has been out since February after sustaining a third concussion.

"I very much appreciate all the help and support I've received from everyone with the club," said Johnson. "It's never an easy decision to retire, but I feel great about what I was able to accomplish, the connections I made in the game, and the opportunities it presented. My top priorities are my health and my young family, and I am looking forward to my future."

Johnson began his professional career with Manchester United and went on to play in 133 total games for English sides Coventry City (2004-05) and Crewe Alexandra (2005-06) on loan, Bradford City (2006-08) and his hometown club Chester City (2008-09).

"On behalf of everyone involved with the club, I would like to thank Eddie for his time with us," said Timbers general manager Gavin Wilkinson. "We understand and respect his difficult decision and wish Eddie and his family all the best."
