Marcus Coker Suspension: Another Bowl Game for Iowa, Another Suspension

Last season, receiver Derrell Johnson-Koulianos and running back Adam Robinson were suspended by Iowa right before the Insight Bowl.

On Tuesday, leading rusher Marcus Coker was suspended for "a violation of the Hawkeyes' student-athlete code of conduct," according to ESPN.

Coker, who replaced Robinson in last season's bowl game, will now miss this year's Insight Bowl, coming off a breakout campaign.

The sophomore rushed for 1,384 yards and 15 touchdowns on 281 carries this season. He was the offensive MVP of the 2010 Insight Bowl, rushing for 219 yards and two touchdowns in the Hawkeyes' 27-24 win over Missouri.

Last season, Johnson-Koulianos was suspended after he was arrested on December 7, 2010. He was charged with possession of controlled substances and unlawful prescription drugs, along with keeping a drug house.

Robinson was eventually dismissed from the football team after he was arrested on marijuana charges.

At the time, it was a big story and one of the biggest shockers of the year. Of course, 2011 has seen its share of surprises, including the Penn State and Ohio State scandals.

For the Hawkeyes, it appears to mark more of a problem with its players than the program itself.

The program went 7-5 this season. Although the Hawkeyes scored an upset over then-No. 15 Michigan on November 5, their season was largely considered a disappointment.

Then again, Iowa ended last season 7-5 and still went on to upset No. 12 Missouri, 27-24.

However, the loss of the Hawkeyes' leading rusher will hurt them substantially on December 30 against the No. 14 Oklahoma Sooners.
