Iowa trolls Nebraska after some Cornhuskers players decline pregame handshake

But Nebraska's players decided not to engage in the handshaking ritual with their opponents. At least one of the four Cornhuskers' captains appeared to shake and look towards the ground as the Hawkeyes players approached.

"Our guys are warming up, doing our pregame and their head coach walked through the warmup," Higgins told reporters after the game. "So we immediately knew what type of game this was."

But emotions remained high even after the game kicked off. Higgins was seen getting close to Rhule when the Hawkeyes were on defense in the first quarter.

Higgins said he had told Rhule during the interaction that "it probably wasn't a good idea to not shake our hands." The Iowa defender offered a three-word response saying, "Who are you?"

Nebraska did manage to take an early 10-0, but the Hawkeyes scored 13 unanswered points. Iowa kicker Drew Stevens made a 53-yard field goal in the final seconds to secure the victory in the rivalry game.

"After the game, because they didn't want to shake our hands before the game, I went up to their head coach and shook his hand," Higgins confirmed. "And told him, 'Good game.'"

At one point during his postgame media session, Higgins asked his teammate, Nick Jackson, to point out the differences that exist within Iowa's program in comparison to Nebraska. 

"Kirk Ferentz - would he ever do something like that?" Higgins asked, to which Jackson quickly replied "no."

"Be a Hawk," Jackson said. "You see the difference."

Ferentz, who has coached at Iowa for more than a quarter-century, declined to offer a strong opinion on what transpired before the game.

"I heard some stuff in the locker room, but I wasn't out there," Ferentz said. "So I didn't see it and really can't comment on it. There are certain pregame etiquette most people follow, but again, I didn't see it."
