Eryk Williamson, a University of Maryland attacker from D.C. United’s youth academy and U.S. under-20 national team, will forego his senior season in order to pursue a pro career, multiple sources told the Insider on Tuesday.

He has signed with an agent and will weigh opportunities with United or clubs overseas. United is planning to tender a homegrown contract offer in the coming weeks in an effort to keep him in the organization. Because of Williamson’s ties to the youth system, he is exempt from the MLS draft next month.

Williamson is from Alexandria, Va., and graduated from T.C. Williams High School. This season, he led the Terrapins with six goals and five assists and earned third-team all-America honors. He also made the Big Ten first team and was named the conference’s top midfielder.

However, he received mixed reviews in college, at times displaying sublime skill but also prone to disappearing from matches.

As part of the U-20 national team this year, he played in all 12 matches and started 10, with one goal and two assists. At the U-20 World Cup in South Korea over the summer, he started four of the five matches as the Americans advanced to the quarterfinals. Williamson then joined Swedish club Hammarby for workouts.

United currently has three homegrown players on the roster: defender Jalen Robinson (Catonsville, Md.), defender-midfielder Chris Durkin (Glen Allen, Va.) and midfielder Ian Harkes (Fairfax). Another homegrown, star goalkeeper Bill Hamid from Annandale, will join Danish club Midtjylland next month after eight season with United.

Williamson is the second prominent local college player this month to leave school early: Georgetown junior goalkeeper JT Marcinkowski signed a homegrown contract with the San Jose Earthquakes.
