Katin Houser made an immediate impact in his Illinois debut, tossing three touchdown passes and running for another score as the Illini defeated UAB 42-23 on Thursday night at Gies Memorial Stadium. The transfer from East Carolina looked sharp, completing 13 of 17 passes for 182 yards with no interceptions. His favorite target, Collin Dixon, hauled in six catches for 70 yards and two touchdowns, while Ca’Lil Valentine powered the ground game with 11 rushes for 88 yards and a score.

Illinois wasted no time establishing control. On their first six offensive plays, the Illini struck twice—first on an 18-yard pass from Houser to Dixon set up by a 65-yard punt return from Mac Resetich, then on a 51-yard touchdown run by Valentine. The fast start gave Illinois a 14-3 lead, but UAB responded. Blazers quarterback Ryder Burton, who finished 18 of 33 for 219 yards and a touchdown, led a scoring drive capped by his own rushing touchdown. Jonah Delange added a field goal to make it 14-13 midway through the second quarter.

The defining moment of the first half came with seconds remaining. Illinois faced a fourth-and-long from their own 46-yard line. Houser launched a 54-yard Hail Mary into the end zone, where the ball was tipped by a UAB defender before Ty Robinson corralled it for the touchdown as time expired. “I thought Katin had a 50-yard arm,” said Illinois coach Bret Bielema. “I think he surprised some people there.” The play gave Illinois a 21-13 halftime lead and shifted momentum firmly in their favor.

UAB coach Alex Mortensen, the son of the late ESPN analyst Chris Mortensen, made sure his team didn’t dwell on the stunning play. “My message was OK, it happened,” he said. “There’s a half of football left.” The Blazers came out with renewed energy, but Illinois’ defense stepped up in the second half. Safety Ismael Kante returned an interception 59 yards for a touchdown in the fourth quarter, effectively sealing the win.

Despite the 19-point loss, UAB showed signs of improvement from a 4-8 season that saw head coach Trent Dilfer fired midseason. The Blazers actually outgained Illinois 413-333 in total yards. Missed tackles plagued Illinois’ new 3-5-5 defensive scheme under coordinator Bobby Hauck. Bielema noted that the team had limited tackling drills during fall camp to avoid injuries after a player was hurt making a tackle.

The night also marked the debut of Illinois’ massive new videoboard, measuring 17,315 square feet—the largest in college football, surpassing Auburn’s 10,690-square-foot board. Fans filled the stadium on a warm, muggy evening, eager to see the revamped Illini.

For UAB, Mortensen, who took over as interim coach last season and was named permanent head coach in December, saw his team fight until the end. Burton’s passing kept drives alive, and Delange connected on three field goals. But the Hail Mary before halftime proved a bitter pill that ultimately tipped the scales.

Illinois next hosts Duke on Sept. 12, while UAB welcomes Louisiana-Monroe the same day. Both teams will look to build on the lessons from this opener.
