Both the Hawkeyes and Scarlet Knights moved the ball inside the 10-yard line earlier in the second quarter, but failed to turn those drives into points.
Rutgers playmaker Janarion Grant took a swing pass 76 yards to the Iowa 3, making three Hawkeye defenders miss in the process.
But Iowa stuffed four straight run plays, including a fourth-down option play at the 1-yard line. Rutgers QB Chris Laviano was drilled by Desmond King, then stopped by Josey Jewell and Bo Bower has he reached for the goal line.
Grant wasn't available as he appeared to hurt his ankle and was carted off the field.
On the series prior, Iowa drove to the Rutgers 10 and went for it on 4th and 5, but Beathard overthrew Jerminic Smith for a turnover on downs.
End 1st: Iowa 0, Rutgers 0
No score after one quarter in Piscataway.
Rutgers probably had the best chance to score, getting to Iowa's 8 before a pass interference penalty and Parker Hesse sack pushed it back to the 36, where the Scarlet Knights punted.
