Rising took part in warmups but was in street clothes for the start of the game. Rising, who has yet to play this season, was given clearance to practice without limitation in early September and was given positive reports by coach Kyle Whittingham this week about how he looked in practice.
Johnson led Utah's comeback win at Baylor two weeks ago, scoring the tying touchdown on a 7-yard fourth-quarter run. That performance led to Whittingham making the switch between the backups, and Johnson started and played well in a 31-7 victory over Weber State last week.
A 6-foot-1, 195-pound dual-threat quarterback with unusual speed for the position, Johnson threw for 193 yards against Weber State. On the season, he has three rushing touchdowns and is averaging 4.5 yards per carry.
Johnson has completed 68.8% of his passes, as he had a significant role as a change-of-pace quarterback in Utah's first two games before becoming the starter.
Rising has led Utah to back-to-back Pac-12 titles, and his status has been one of the biggest questions hanging over the sport this month. Whittingham has told reporters that the medical clearance on Rising's return isn't up to the Utah medical staff.
Rising's ACL was repaired by noted orthopedic surgeon Dr. Neal ElAttrache, and earlier in the month, Whittingham told the Deseret News of ElAttrache: "The ultimate guy that says thumbs-up, thumbs-down for playing, and right now we don't have that thumbs-up."
Rising is one of the most accomplished players in the sport, as he threw for 3,034 yards with 26 touchdown passes last season before the injury in the Rose Bowl. With Rising under center, Utah has registered back-to-back 10-win seasons. Utah is 3-0 without him this year and plays UCLA in a battle of undefeated teams.
