Iowa running back Marcus Coker has been suspended from the Dec. 30 Insight Bowl against Oklahoma after violating the university's student-athlete code of conduct.

The university announced the suspension Tuesday without providing details.

Coker, who is a sophomore from Beltsville, Md., will not travel with the team to Tempe, Ariz., for the game between the Hawkeyes (7-5) and the Sooners (9-3).

Coker's rushing total of 1,384 yards this season ranked fourth in school history. He was also the offensive player of last season's Insight Bowl, when he set Iowa bowl records for rushing attempts (33) and rushing yards (219) in the 27-24 win over Missouri.
