If you ever wanted to compete against Packers running back Ahman Green, Tuesday is your chance to do so in the virtual world.

As part of the "Game With Fame" Session, Xbox gamers can challenge him in a game of Halo2 on September 20 from 2 to 3 p.m. (CST). Participants can also chat with him through a headset hooked up through Xbox Live.

Anyone with an Xbox hooked up to a television screen can play against Green. A gamer tag -- similar to an Instant Messenger screen name -- listed as "ahmanlive" will come across your Xbox and flash Green's name allowing you to play.

In the game Halo2, a genetically enhanced super soldier aims to prevent the destruction of mankind.

Other celebrities who have participated in the Xbox Live "Game with Fame" program include Ludacris, The Strokes, Hoobastank, Three Doors Down, Incubus and Buffalo Bills running back Willis McGahee.

Green ranks second on the all-time Packers' rushing list with 6,906 yards and has rushed for more than 1,000 yards for five consecutive seasons.
