The college career of Iowa defensive lineman Noah Shannon is over. Shannon was suspended for the season by the NCAA as part of a gambling investigation. Hawkeye coach Kirk Ferentz says his appeal has been denied.

Shannon did not wager on an Iowa football game but reportedly wagered on a game involving another Iowa sports team.

Ferentz says he does not agree with or understand the decision.

Shannon passed up the NFL Draft to return for a sixth year and Ferentz says he will remain involved in the program.

The 25th ranked Hawkeyes take a 2-0 record into a game at home against Western Michigan and Ferentz says a key this week is not looking ahead to next week’s Big Ten opener at seventh ranked Penn State.

Ferentz says all he has to do is point to the recent history of the series.
