The grandfather of Iowa star linebacker Jack Campbell tragically died in a car crash in Nashville on Friday after traveling to Tennessee to see his grandson play in what will likely be his final college football game.

William Smith Jr., 76, was pronounced dead at Vanderbilt University Medical Center after being involved in a single vehicle-pedestrian incident late Friday evening, the university said in a statement on Saturday.

"Our hearts are with Jack and his entire family as they grieve the tragic death of their grandfather and father, William Smith, Jr.," coach Kirk Ferentz said in a statement provided by the school.
