COLUMBUS, Ohio -- Forward Zach Williams was suspended Monday for the rest of the season by Ohio State coach Jim O'Brien because of his conduct during the Big Ten tournament championship game.

Williams was sent off the court Sunday during the Buckeyes' loss to Illinois in Chicago for arguing with an assistant coach. The suspension means Williams will not play in the NIT.

In addition, the Big Ten ruled that Williams violated the conference's sportsmanlike conduct agreement after officials reviewed a videotape and saw him strike a Wisconsin player during a quarterfinal game Friday. No disciplinary action was announced by the conference, but Ohio State said the Big Ten agreed with the suspension.
