Harvard's high scoring 'Local Line' of Billy Corkery. Dave Hynes and Bob McManama will not be allowed to play for the United States national team in next week's World Cup hockey competition according to a ruling by the Ivy League dean's committee on coordination and eligibility.

The three players received official notice of the league's refusal last Saturday, although they had learned that the ruling was unfavorable December 9. They were scheduled to leave for Colorado Springs. Colo, this weekend to play in games there and later in Minneapolis, against teams from Canada, Russia and Czechoslovakia.

The rule cited by the committee states that: "A student shall not engage in outside competition in any sport while he is a member of a varsity of freshman team in that sport and during the season of the sport in question." The rule book does, however, allow for exceptions, but the wording is vague and left up to the committee to decide upon.

"It's an umpire's call, like interference in football. You have to call 'em as you see 'em," Robert E. Kaufman. Harvard's representative on the committee, said yesterday.

Kaufman, who was not allowed to vote on the case because it concerned Harvard students, said that the major reason for the ruling was that the players were chosen on an all-star basis.
