The 30-year old former Leeds winger has penned a multi-year extension to remain with the Red Bulls for the foreseeable future which has delighted sporting director Ali Curtis.
"Lloyd has been a key player for this club the past few seasons and we're very excited to have him in a Red Bull uniform for the coming years," Curtis said in a statement.
"Lloyd is a very dynamic player on the wing and provides a great attacking threat for us."
Sam, who also played for Charlton Athletic, arrived at the Red Bull Arena in August 2012 and has since made 70 appearances for the MLS club, scoring 11 goals and providing 12 assists.
