Montana State's Harry Clark posted a fine score in winning the decathlon at the Clarence Robison Invitational track and field meet Friday at BYU in a competition that was marred by an accident.

Mike Murphy, a Weber State freshman from Gillette, Wyo., was listed in critical condition in the intensive care unit at Utah Valley Medical Center Friday evening after undergoing emergency surgery. Doctors reportedly operated to relieve internal bleeding in the back of the head at the base of the skull. According to Brent Harker of the BYU public communications staff, Murphy is "going to be all right. There are no broken bones, no muscle damage. He's expected to recover."According to the BYU sports information office, Murphy apparently overshot the padded pit in the pole vault and struck his head on the ground.

The decathlon competition concluded later in the day, with Clark posting a score of 7,613. BYU's Dave Draney was second with a score of 7,399, followed by teammate Scott Peterson, who had 6,780 points.

The remainder of Friday's meet consisted of trial heats. The finals will be held today, beginning with the hammer at 11:30, the rest of the field events and the 10,000-meter run at 1:15 and the bulk of the running events at 2.
