Brook Madsen sacrificed his body for Southern Utah's upset victory over Montana Saturday.

He rushed for 145 yards and four touchdowns but broke his arm diving into the end zone after a 35-yard run with 3:08 remaining that sealed the win for the Thunderbirds in their season-opener."That's a major blow to our offense," said Southern Utah coach C. Ray Gregory. "Somebody else is really going to have to step up."

He may not have to look much farther than sophomore quarterback Matt Cannon, who rushed 34 times for 209 yards and another score as Southern Utah handed Montana (1-1) only its second home loss in the last four years.

"The feeling I had on the sidelines was we did not go out with the idea that these guys were as good a football team as they are," said Montana coach Mick Dennehy said. "I don't think we were at our best today."

Brian Ah Yat threw for 423 yards and four touchdowns, including three to Justin Olsen. But he also threw three interceptions.
