The World League of American Football has approved the use of radios in quarterbacks' helmets for its first season, which begins in March.

Tex Schramm, WLAF's president, had hoped to get the innovation into the National Football League when he was president of the Dallas Cowboys.

"Technological innovations will be a trademark of the World League," Schramm said. The WLAF is an NFL subsidiary.

Schramm said coaches' ability to communicate with their quarterbacks by radio will be a boon to the no-huddle offense.

"Not only will this heighten the excitement level with a final two-minute style of play, but it will speed up the tempo and shorten the overall playing time of our games without decreasing the number of plays," he said. . . .

On June 23 at 2 p.m., the Washington Redskins and Dallas Cowboys will play football at RFK Stadium. The good old Redskins and Cowboys.

How about John Riggins, Roger Staubach, Bob Hayes, Drew Pearson, Pat Fischer, Dave Butz, Ron McDole and Mark Murphy?

Redskins and Cowboys of the past will come back to square off in flag football for charity. Tickets are $15 for reserved seats, $10 for adult general admission, $5 for children; available by calling 432-0200. A portion of the proceeds will go to the March of Dimes Birth Defects Foundation.

Yesterday at the Grand Hyatt, some of the old-timers gathered to chat about, well, the old times. Riggins looked downright scholarly in wire glasses -- and quite trim too. Diron Talbert gave Harvey Martin a wreath, in honor of Martin's wreath-tossing escapade in the Washington locker room after the Cowboys' 35-34 season-ending win over the Redskins in 1979.

"This is cute," Martin said to Talbert.

"We didn't like each other a whole lot," Martin said of the Cowboys and Redskins. "Now, we can sit down, drink a Coca-Cola and smile." . . .

The British Columbia Lions found just what they wanted when they opened their mail Wednesday -- a contract signed by Major Harris, the West Virginia University quarterback.

"The Major signed his contract -- I've seen it," said General Manager Joe Kapp. "We're excited . . . Major is getting major league money to play in the Canadian Football League."

Harris, 22, reached an agreement in talks last week during a visit from Coach Larry Kuharich, but the signed contract took more than a week to reach the anxious B.C. front office.

Harris, third in the 1989 Heisman Trophy balloting, elected to leave school before his senior season, but wasn't selected in the NFL draft until the 12th and final round, by the Los Angeles Raiders.

The Lions also have NFL veteran Doug Flutie on their negotiation list, but his rights may be traded to another CFL team now that Harris has signed.
