IHL EXPERIMENT: A unique weekend in professional hockey history is set to take place at the end of the March in Las Vegas.

On March 27 and 28, the Detroit Vipers will visit the Thomas & Mack Center to play the Las Vegas Thunder in two games using a four-quarter format. It is the first time a regular season hockey game has been altered from three periods.

These experimental fnrmatq have been designed by the International Hockey League in consultation with the NHL. Fan and player reaction will be surveyed following the games.

"This experiment is part of an ongoing process of evaluating all aspects of our game," said Briaii Burke, NHL Senior Vice-President and Director of Hockey Operations. "We appreciate the cooperation that the IHL lent to this."

Each quarter will be 15 minutes in duration. At the end of the first and third quarters an eight-minute break will allow the ice to be resurfaced. "Half-time" will commence at the end of the second quarter and last for 14 minutes. A standard shootout will follow the fourth quarter should the game end in a tie.

Fox Sports Net will televise the March 28 game to a national audience.

DOWNHILL CANCELED: Fog forced race officials to cancel the season-ending women's downhill today in the World Cup finals in Crans Montana, Switzerland.

ROSE SPEAKS . . . OOPS!: Pete Rose's one-hour talk to some attentive Cincinnati Reds minor leaguers might have hurt the career hits leader's bid to reverse his lifetime ban.

Rose gave an impromptu motivational speech to nearly 100 minor leaguers, including son Pete Jr. Rose had permission from the team to watch his son work out, but there was no prior indication he would speak.

Baseball said the talk violated the lifetime ban Rose agreed to nearly nine years ago. The Reds might be fined as a result of Rose's speech, a baseball official said, speaking on condition he not be identified.

Rose, who agreed to accept the ban following baseball's investigation of his gambling, applied for reinstatement Sept. 26.

Meanwhile, All-Star shortstop Barry Larkin, unable to protect himself defensively because of a perforated disk in his neck, needs surgery and will be out at least 4-to-6 weeks. Surgery to remove a protrusion from a vertebrae in his neck is scheduled for Friday in Cincinnati.

Each member of the winning team, for example, will win a new shotgun, and each member of the runner-up team will receive a .22 caliber rifle. Entry deadline is March 18. For information call 298-7516.
