FC Dallas has re-signed defender and former North Carolina standout Zach Loyd.
"I'm excited. I've been there four years now, so I really feel like part of the family," Loyd told FCDallas.com by phone. "I'm excited for the new season and for the things to come at FCD. I think we've got a good group of guys and going forward with the group of guys we have, we can turn things around and have a good 2014."
Drafted fifth overall by FC Dallas in the 2010 MLS SuperDraft, Loyd appeared in 111 of the club's 132 MLS regular-season matches in the past four seasons, second only to Jair Benitez (114). The UNC product has scored three goals and added seven assists in 102 starts. He recorded his lone goal of the 2013 season in a 3-0 win against the Houston Dynamo in Lamar Hunt U.S. Open Cup competition on June 12.
"It was always a priority for FC Dallas to sign Zach to a new agreement," said FC Dallas Technical Director Fernando Clavijo. "It was not until the season was over that we started to make progress. Zach has been a big part of FC Dallas for the last four seasons and we are ecstatic to have him back."
Loyd logged career highs in games played (32), games started (31), minutes played (2,696) and goals scored (2) during the 2012 campaign. He also had three assists, two of which were game-winning assists.
Loyd made his professional debut in FC Dallas' second match of the 2010 season, playing a full 90 minutes in a 2-2 draw with the Columbus Crew on April 10 at Toyota Stadium.
Loyd earned the first of his three caps for the U.S. Men's National Team by starting and playing 73 minutes against Chile on Jan. 22, 2011.
Former Tar Heel standout Michael Farfan is making the jump south of the border to join Liga MX power Cruz Azul after three seasons with Philadelphia Union of MLS.
Farfan appeared in 82 games over three seasons for the Union, notching four goals and nine assists. He was a last-minute addition to the MLS All-Star team roster in 2012.
