MLS Notes: MLS is reviewing an altercation between struggling MetroStars forward Clint Mathis -- who is out of contract at season's end -- and a fan at Giants Stadium following Saturday's 2-0 loss to the New England Revolution, according to the New York Daily News... Tim Leiweke, the president of lead MLS investor Anschutz Entertainment Group, told a gathering of Los Angeles Galaxy season-ticket holders that the league would add two teams in 2005: one in Cleveland and one operated by Mexico's Chivas in a yet-to-be-determined city, according to a report in the Los Angeles Times. San Diego has been cited as the front-runner for the Chivas club. Leiweke said MLS hopes to add two more teams in '06 or '07, and that AEG hopes to sell off three of its five teams. However, MLS chief operating officer Mark Abbott later told the New York Times that expansion is not yet a done deal, adding that the league has purchased the pre-Libertadores Cup.
