Iowa offensive lineman Riley Reiff, cornerback Shaun Prater and receiver Marvin McNutt were named today to preseason watch lists for college football awards.

Reiff, already named to Playboy's preseason all-American team, is one of 65 players named to the watch list for the Outland Trophy, presented annually to the best interior lineman in college football, while Prater landed a spot on the watch list for the Bronko Nagurski Trophy and McNutt was named to the watch list for the 2011 Biletnikoff Award.

A 6-foot-6, 300-pound junior offensive tackle from Parkston, S.D., Reiff is one of three returning starters on the Hawkeye offensive line. The second-team all-Big Ten selection has started 24 games in two seasons at Iowa.

He is one of 13 Big Ten players on a watch list for Outland, a group that also includes offensive tackles Jeff Allen of Illinois and Kelechi Osemele of Iowa State.

Prater is among candidates for the Nagurski, which like the Outland is presented by the Football Writers Association of America. He is among 87 candidates for the award given to the college game's top defensive player.

A 5-11, 180-pound senior cornerback from Omaha, Neb., Prater is a three-year letterwinner and returning first-team all-Big Ten pick. He finished with 68 tackles a year ago and had four interceptions, a number that tied for fourth best in the conference.

One of 10 Big Ten players on the Nagurski watch list, Prater is joined on the list by Illinois defensive tackle Akeem Spence and Iowa State linebacker Jake Knott.

McNutt, a 6-4 senior from St. Louis, is on the watch list for the Biletnikoff Award, presented annually to the top receiver in college football.
