The Portland Thorns have traded longtime midfielder Allie Long.

The Thorns announced Thursday that the club had acquired the rights to Australian forward Caitlin Foord and a 2020 conditional natural second-round draft pick from the Seattle Reign in exchange for Long.

"We are very appreciative of Allie's contributions to the club over the past five seasons," said Thorns general manager and president of soccer Gavin Wilkinson in a prepared statement. "She accomplished a great deal during her time in Portland, winning two NWSL Championships and achieving her goal of making it to the national team, and we wish her all the best."

Long had been a central figure on the Thorns since the league's inaugural season in 2013.

Her success with Portland earned her a spot with the U.S. Women's National Team in 2016 and she competed in the Olympics in that same year. She appeared in 100 career matches during her time with the Thorns, becoming just the third player in NWSL history to accomplish that feat with a single club. During her five seasons in Portland, Long recorded 30 goals and 13 assists and was twice named to the NWSL Best XI (2015, 2016). She also earned a spot on the NWSL Second XI in 2014. Her most memorable moment for Portland may have come in 2013 when she scored the game-winning goal in the semifinals of the 2013 NWSL playoffs to lead the Thorns to the NWSL Championship Game.

But Long saw her playing time diminish toward the end of the 2017 season when Thorns coach Mark Parsons changed his formation and made the decision to start Lindsey Horan and Amandine Henry over Long.

Heading into the offseason, there was speculation that Long could be on the move. Long is aiming to compete in the 2019 Women's World Cup and will likely have a better opportunity to start in Seattle as she continues to gear up for the international tournament.

Foord spent three seasons with Sky Blue FC (2013-15), recording three assists in 46 appearances and earning a spot on the NWSL Second XI in 2013. The Australia Women's National Team forward has earned 57 caps, scoring 10 goals on the international stage. She has also appeared in two FIFA Women's World Cups (2011, 2015), as well as the 2016 Rio Olympics. She was named the Asian Women's Footballer of the Year in 2016. Most recently, Foord competed for Sydney FC.

"Caitlin is one of the most explosive and exciting players in the world," said Parsons in a prepared statement. "She has the ability to create and finish in various ways. Her enthusiasm and tireless work rate on both sides of the ball will bring a new dimension to our team."

Additionally, the Thorns are also working on another trade that is expected to be announced soon, a source confirmed to The Oregonian/OregonLive.
