The athletic department said Tuesday that Latham was awaiting the resolution of a proceeding with the school's office of student ethics. The school did not provide additional details about what led to the suspension and said it would have no further comment until the process ends.
But the indefinite suspension begins immediately, meaning Latham probably will miss Saturday's game between the Hoosiers (4-0) and No. 1 Ohio State (4-0). Latham has 10 tackles in three games and leads the team with five tackles for loss. The junior is tied for second in sacks with two.
Saturday's game is the only one in Big Ten play pitting two unbeaten teams against one another.
