American midfielder Stuart Holden has agreed to a contract extension with Bolton, just eight months after joining the English Premier League club from Major League Soccer's Houston Dynamo.

The 25-year-old from Texas, who was born in Scotland, had been signed through this season. The club announced Thursday he agreed to a deal through 2012-13.

Holden initially joined Bolton in January on a short-term deal. The Netherlands' Nigel de Jong broke Holden's right leg during a March 3 exhibition against the U.S., restricting Holden to just three appearances last season, but he has started each of Bolton's six Premier League matches this season.

A member of the U.S. World Cup team, Holden says the injury "made me more determined to make an impact when I came back for preseason."
