Iowa senior linebacker Jack Campbell helped the Hawkeyes defeat the Kentucky Wildcats on Saturday in the Music City Bowl in Nashville, but the 22-year-old received some devastating news afterward.

Campbell's grandfather, William Smith Jr., who was 76, died Friday night after a car struck him as a pedestrian, per ESPN's Adam Rittenberg. He was transported to Vanderbilt Medical Center, where he was pronounced dead.

Campbell's parents decided not to tell him until after the game so he could have "one last time to play with his Iowa Hawkeye teammates," the school said, via Adam Hensley of Hawk Central.

Iowa coach Kirk Ferentz said in a statement:

Campbell played a significant role in Iowa's 21-0 win over Kentucky, posting one sack, 10 tackles and two tackles for a loss.

He had an outstanding 2022 campaign for the Hawkeyes. In 12 games entering the Music City Bowl, he had posted one pass breakup, one forced fumble, one fumble recovery, two interceptions, 115 tackles and 3.5 tackles for a loss.

Campbell was named Big Ten Defensive Player of the Year and also became the first Hawkeye to take home the Butkus Award as the nation's top linebacker.
