Iowa will be without one of its top playmakers against Michigan State this weekend.

Iowa is suspending receiver Ihmir Smith-Marsette for at least this week’s game vs. the Spartans, coach Kirk Ferentz announced Sunday.

Police arrested Smith-Marsette for operating while intoxicated in the hours after Iowa’s 21-20 loss to Northwestern.

Police pulled over Smith-Marsette after after clocking him at 74 miles per hour in a 30 mile per hour zone. Smith-Marsette also failed multiple field sobriety tests.

“I was disappointed to learn that Ihmir Smith-Marsette made a number of dangerous and potentially harmful decisions early this morning,” Ferentz said in a statement. “First and foremost, I am thankful no one was hurt.

“I spoke with Ihmir this morning, and he was apologetic and disappointed in himself. As a coach and parent, I understand the personal pain that comes with making these types of decisions. These situations can be defining moments for all students. It is my responsibility to hold our players accountable and help them learn and succeed.”

Smith-Marsette is a senior who has 10 touchdowns in his career. He caught 44 passes for 722 yards as a junior.

If Ferentz opts to suspend Smith-Marsette for a second game, he would miss Iowa’s contest vs. Minnesota.

Iowa and Michigan State kick off at 12 p.m. on Saturday.
