Playing without Nate Sudfeld or Jordan Howard, Indiana's offense struggled in the first half as the Hoosiers trail Penn State 20-7 at halftime in State College, Pa.
Penn State quarterback Christian Hackenberg hit wide receiver Brandon Polk on a 39-yard touchdown pass for Penn State's first score of the game.
Indiana later responded when quarterback Zander Diamont had back-to-back completions to wide receiver Isaac Griffith for a total of 31 yards to put Indiana in the Penn State redzone, then a 12-yard touchdown run on a quarterback keeper to tie the game. Diamont had started the game 0-for-6 on pass attempts before the consecutive completions to Griffith.
The Hoosiers had a pair of opportunities to take the lead, but ended up unable to capitalize on both.
The first was an onside kick on the ensuing kickoff after Diamont's touchdown. Indiana recovered, but went 3-and-out and was forced to punt. Penn State drove to the Indiana 43, where the drive was stalled after a fumbled handoff was recovered by the Hoosiers.
Penn State regained the lead with 5:40 remaining in the first half on a another 39-yard touchdown pass from Hackenberg, though the second time it was caught by wide receiver DaeSean Hamilton instead of Polk. Penn State kicker Joey Julius missed the ensuing extra point attempt.
The Nittany Lions closed the first half with a 3-minute, 8-second 62-yard drive capped off by a 1-yard touchdown run by Hackenberg.
Indiana was outgained by Penn State 310-107 in total yards of offensive in the first half. The Hoosiers will receive the opening kickoff of the second half.
