There is "a battle being waged" between Dolphins Owner Wayne Huizenga and the NFL over a 220-foot rotating ad sign directly behind one set of goal posts at Pro Player Stadium, according to Mike Freeman of the N.Y. TIMES. Freeman: "It is not on the level of Jerry Jones and the NFL, because Huizenga cooperates with the league more than Jones. But the result is the same: Huizenga does what he wants and the league isn't happy about it." An NFL spokesperson said that the league has written to Huizenga, "citing its unhappiness with the placement of the advertising." The NFL reportedly also told the team "that no advertisements can be placed at field level." The situation is being "closely watched by many in the league," and fact, "many observers expect" the league to soon fine the Dolphins (N.Y. TIMES, 9/14). AMBUSHED: In Toronto, William Houston reported that TSN execs are "upset" over the CFL Hamilton Tiger-Cats selling a sign advertisement to a sports TV "rival." The ad in Hamilton's Ivor Wynne Stadium promotes the cable service Headline Sports, and is "visible" on TV broadcasts. TSN, which carries 40 CFL games, wants the ad removed, but Houston wrote the Tiger-Cats "[need] the money." The matter is before the league. The ad space is "rumored" to have been sold for C$12,000 (Toronto GLOBE & MAIL, 9/13).
