He is the younger brother of retired NFL cornerback and New York Jets head coach Aaron Glenn.
He played in an AFC wild card game at Oakland on January 12, 2002, and had one special teams tackle.
Although he was used primarily as the team's nickel linebacker, he did start once (game 14 against Pittsburgh) and ended up with 47 tackles on the season.
He had eight tackles on defense including six solo, and one fumble recovery on special teams before being placed on IR on November 14 with an injured knee.
That same day, Vikings' head coach Brad Childress announced that Glenn was retiring from football.
