The Washington Redskins finally got their wish. After complaining about National Football League scheduling that has sent them to Dallas late in the season 10 times in the last 12 years, they will play the Cowboys at Texas Stadium to open the 1985 National Football League season on ABC's "Monday Night Football" Sept. 9.

According to a schedule that will be released today by the league, this will be the first of three Monday night appearances for the Redskins, who are one of the estimated half dozen NFL teams who will play three times on "Monday Night Football."

The Redskins will play at RFK Stadium against the St. Louis Cardinals on Monday night, Oct. 7, and will meet the New York Giants on Monday night, Nov. 18.

Redskins Coach Joe Gibbs and General Manager Bobby Beathard were traveling and could not be reached for comment yesterday, but there is no doubt they are pleased with any schedule that brings the Cowboys to town late in the season.

After last season's schedule was announced, and the Redskins' request to play in Dallas during the teams' first meeting was denied, Gibbs and Beathard publicly questioned the league's scheduling procedure.

"I don't know why it's a problem," Gibbs said. "We would obviously rather have our first shot against Dallas down there and have them come to our place late in the season. We'd like to at least have it on an alternating basis."

Added Beathard: "In a lot of cases, it boils down to a very meaningful game late in the year (against Dallas) and that game is always in Dallas."

NFL spokesman Joe Browne told the Redskins then that the NFL would try to make the change for 1985.

The rest of the Redskins' 1985 schedule will include home games against the Super Bowl champion San Francisco 49ers, Detroit Lions, Cincinnati Bengals, Houston Oilers, Philadelphia Eagles and Dallas.

The rest of the road schedule includes games at Atlanta, Chicago, Cleveland, Pittsburgh, Philadelphia, New York (Giants) and St. Louis.
