MADISON, Wis. -- Angry about a late timeout, Michigan Coach Juwan Howard began arguing in the postgame handshake line.
Moments later, he hit a Wisconsin assistant in the head, and mayhem followed.
The Wolverines' inability to boost their NCAA Tournament credentials was the least of their concerns after a 77-63 loss Sunday at No. 15 Wisconsin. Their head coach could be facing major discipline.
Howard hit Wisconsin assistant Joe Krabbenhoft after jawing with Wisconsin Coach Greg Gard during the handshake line. The Big Ten said it planned to "take swift and appropriate disciplinary action when it completes its review."
During his postgame news conference, Howard said he didn't like Wisconsin calling for a timeout with 15 seconds left and the Badgers leading by 15.
"I thought it was not necessary at the moment, especially being a large lead," Howard said.
Gard said he called the timeout because his reserves were in the game and only had four seconds to get the ball past midcourt. A timeout gives them 10 seconds.
"I was not going to put them in position, where the ball had already gotten knocked out of bounds, to have to break a press in four seconds," Gard said.
After the game, Howard pointed a finger at Gard while complaining about the late move. Later on, Howard reached through a crowd to get to Krabbenhoft -- replays showed Howard had his hand open as he struck Krabbenhoft on the left side of the head.
Players from each side got involved in the skirmish, and video appeared to show Michigan's Moussa Diabate and Wisconsin's Jahcobi Neath throwing punches.
Howard said he reacted after someone from Wisconsin put hands on him. He said that "at that point, I felt it was time to protect myself."
Video showed Gard had his hands touching Howard's arm or wrist area while trying to explain why he called the timeout.
"Someone touched me, and I think it was very uncalled for, for them to touch me, as we were verbalizing and communicating with one another," Howard said. "That's what escalated it."
Wisconsin Athletic Director Chris McIntosh said he already had contacted Big Ten Commissioner Kevin Warren about the situation, adding that Wisconsin had staff members who were "affected and injured."
"There's no room, no space for conduct like that in any competition, much less a Big Ten competition," McIntosh said. "The Big Ten takes pride in sportsmanship. The Big Ten takes pride in acting with class. That didn't happen today."
Michigan Athletic Director Warde Manuel issued a statement saying that he had apologized to McIntosh and that Michigan President Mary Sue Coleman had contacted Wisconsin Chancellor Rebecca Blank "to apologize for the totally unacceptable behavior."
"There is no excuse for any of our staff or student-athletes to get into a physical altercation with others regardless of instigating factors," Manuel said.
The Big Ten issued a statement saying that it's assessing the incident. Howard said he'd respect whatever decision the Big Ten makes.
"We will review the situation more thoroughly and work with the Big Ten Conference as they determine their disciplinary actions and will determine if further disciplinary actions are warranted," Manuel said.
This isn't Howard's first high-profile incident with another Big Ten coach.
Last season, Howard got into a shouting match with then-Maryland Coach Mark Turgeon during the conference tournament. Howard had to be restrained. He drew two technical fouls and was ejected from a game Michigan ended up winning 79-66.
Johnny Davis scored 25 points to help Wisconsin (21-5, 12-4) break open a close game. Wisconsin outscored Michigan 44-25 over the last 18 1/2 minutes.
Davis went on a personal 9-0 run and blocked a shot in a span of 2 minutes, 12 seconds to give the Badgers a 56-41 lead.
Hunter Dickinson scored 21 points for Michigan (14-11, 8-7), which shot just 4 of 25 from 3-point range. Eli Brooks had 14 points, and DeVante' Jones finished with 11.
In other Top 25 men's games Sunday, Jaden Ivey scored 25 points, Zach Edey added 15 points and No. 5 Purdue ended Rutgers' recent run of success against ranked teams, winning 84-72. Rutgers had won its last four games, all against teams in the Top 25. The Scarlet Knights also had beaten Purdue in December. Ivey did much of his scoring at the line, hitting 15 of 18 free throws. Trevion Williams and Sasha Stefanovic each scored 11 points and Mason Gillis 10 points for the Boilermakers (24-4, 13-4 Big Ten). ... Jared Bynum made two free throws with 38 seconds left in overtime, capping No. 8 Providence's rally from a 19-point deficit for a 71-70 victory over Butler. Down 43-24 early in the second half and still trailing by seven points with 2 1/2 minutes left in regulation, the Friars (22-4, 12-2 Big East) pulled off the comeback. ... J'Wan Roberts' dunk with 1.3 seconds remaining in double overtime lifted No. 14 Houston over Wichita State 76-74. It was Roberts' only basket of the game and followed Wichita State's Craig Porter hitting a tying three-pointer with 5.4 seconds remaining in the second overtime. Josh Carlton scored 11 of his 23 points in the two overtimes, finishing 9 of 14 from the floor for the Cougars (22-4, 11-2 American Athletic Conference).
