Derrell Johnson-Koulianos just took a sledgehammer to his NFL career.

Iowa’s all-time leading receiver was arrested on drug charges on Wednesday and has been accused of “keeping a drug house” at his home several blocks from campus. He’s also being charged with possession of cocaine and marijuana and apparently tested positive for both upon his arrest.

Good grief.

According to a report by ESPN.com, he could face up to 7 ½ years in prison and multiple fines. His roommate, 21-year-old Brady Cooper Johnson, was also charged after police raided their Iowa City home and discovered marijuana, more than $3,000 in cash, a digital scale and other items used to sell drugs.

Iowa coach Kirk Ferentz immediately suspended Johnson-Koulianos from team activities as soon as he received word of the charges and obviously the receiver won’t play against Missouri in the Insight Bowl on December 28.

The senior received first-team All-Big Ten honors and finished the regular season with 46 catches for 745 yards and 10 touchdowns. He became Iowa’s career leader in receptions and receiving yards and was the first player ever to lead the Hawkeyes in receiving his first three seasons.

I’m not a lawyer and therefore I don’t want to speculate on what Johnson-Koulianos faces from here on out. But it’s probably safe to assume that he can kiss any dreams of playing in the NFL goodbye.
