The Washington Capitals made it official yesterday: their radio broadcasts next season will be on WMAL-630. Ron Weber, who has seen every game the team has ever played, will continue to do the play-by-play.

WTOP had broadcast the games since the franchise was founded 12 seasons ago.

Under the three-year contract, the team will buy its air time from WMAL, do its own production of the broadcasts and sell its own ads. Weber, in effect, will be a Capitals employe.

The Capitals released five players who mainly played for Binghamton last season: left wing Andre Hidi, left wing Daryl Evans, right wing Mike Siltala, center Martin Bouliane and defenseman Timo Blomqvist. All have cleared waivers. The team signed five of its 1985 draft choices -- Rob Murray, Bill Houlder, Larry Shaw, Claude Dumas and Steve Hollett -- who all have a year of junior hockey eligibility remaining. The team also announced that Vito Cramarossa, John Druce, Kris King and Ed Kastelic will play in the organization, either in Washington or Binghamton.

COLLEGES

Defensive back Donovan Small of the University of Minnesota nearly killed himself trying to cut a frozen chicken in his apartment. The knife slipped and cut the femoral artery in his right leg. Doctors at Hennepin County (Minn.) Medical Center worked on the artery two hours, then spent two more hours controlling bleeding.

"It was a scary situation," Coach John Gutekunst said. "He can move his leg now, but it is real sore. We are told by the doctors that Donovan is going to be all right." . . .
