On Thursday night, Winchester High School will retire number 20 in honor of former wrestler Glen Doherty, one of four Americans killed in a terror attack that began on the US Consulate in Benghazi, Libya, on Sept. 11, 2012.

The ceremony will start at 6:30, prior to the Sachems’ varsity wrestling match against Woburn, with honor guards and the Woburn Police Department assisting in the proceedings.

As a tribute to Doherty, Sachem athletes will wear camouflage uniforms in a number of athletic events through Feb. 17. Doherty, class of 1988, was a fierce competitor on the wrestling mat and tennis court at Winchester.

He will join Joe Bellino (27), Joe Murphy (22), and Chris Mitropoulos (44) on the “Wall of Honor” in the Winchester High fieldhouse.

T-shirts, sweatshirts, and jerseys will be on sale to support the Doherty Foundation.
