Jon Hays had two touchdown passes, Moe Lee returned a fumble 57 yards for a score, and Utah held on for a 24-21 victory after No. 25 BYU missed two last-second field-goal attempts Saturday in Salt Lake City.
Fans rushed the field when time appeared to expire after BYU's Riley Nelson threw an incomplete pass. But replays showed one second remained, and officials sent the fans to the sidelines.
The Utes (2-1) then blocked Justin Sorensen's 51-yard attempt, but BYU (2-1) got a second shot because the crowd rushed the field while the play still was alive, resulting in a 15-yard penalty.
Riley Stephenson then came on for a 36-yard attempt that clanked off the left upright, sending the frenzied crowd back on the field for good.
