New England Revolution defender Kevin Alston has taken an indefinite leave of absence to undergo treatment for chronic myelogenous leukemia (CML), a rare but treatable form of leukemia, the club announced Monday.
Alston's medical treatment is not expected to require hospitalization and he is expected to return to play in the future.
"The Revolution fully supports Kevin as he begins treatment," Revolution general manager Michael Burns said in a statement. "Right now, the most important thing for Kevin, and his family, is to concentrate on returning to full health. Kevin's had a tremendous attitude since the diagnosis and his positivity is an inspiration for all of us."
Alston, 24, started all four of the Revs' games this season at left back. New England drafted him 10th overall in the 2009 MLS SuperDraft out of Indiana University. He ranks ninth on the Revs' career charts in games played, and eighth in games started. Alston also started the 2010 MLS All-Star Game.
The Revs play the Seattle Sounders on Saturday.
