IOWA CITY — Iowa Coach Fran McCaffery walked off the court after the win and waved for his team to follow him to the locker room without shaking hands with North Dakota's players and coaches.

It was a wild ending to an otherwise vanilla game that the Hawkeyes won 84-73 on Tuesday night.

McCaffery was irritated with what he considered a few unnecessary and chippy plays in the closing moments of a game that Iowa led by 16 points with three minutes to go.

The most prominent play happened when North Dakota's Corey Baldwin tried for a steal and score with only three seconds left when Nicholas Baer was holding the ball to run out the clock and end the game.

"I wasn't pleased with how the game ended and the things that happened," McCaffery said. "I don't think they teach that kind of stuff, but I was not having it. That's not the way to play."

McCaffery didn't give a direct answer when asked what specific plays bothered him.

"Were you at the game?" he said. "Well, then you should know what I didn't like."

North Dakota's players and coaches lined up for the postgame handshake, then looked surprised that Iowa wasn't there to meet them. Several Fighting Hawks players threw their hands up in frustration.

"They're not malicious kids, they're good kids," said North Dakota Coach Brian Jones, a former assistant at Iowa under Steve Alford. "They're just trying to compete until the final horn goes off. That's all."

Peter Jok and Jordan Bohannon each scored 18 points to help the Hawkeyes (7-5) win their fourth straight. Cordell Pemsl had nine points and a career-high 11 rebounds.

Iowa pulled away with a 16-0 run in the middle of the first half when North Dakota went six minutes without scoring. The Hawkeyes forced eight turnovers on nine possessions during that stretch.

Quinton Hooker scored 18 points to lead North Dakota (5-5). Conner Avants added 17 points and Drick Bernstine had 10 points, 14 rebounds and eight assists.

North Dakota's Cortez Seales played only seven minutes after a first-half collision. Jones said Seales was getting checked for concussion-like symptoms. Seales scored two points. Seales played his high school ball at North Scott. 

Iowa's Tyler Cook missed his sixth straight game with a finger injury. McCaffery said Cook could possibly return on Thursday, but it's likely the freshman will be held out until Big Ten opener next week.
