Fullback Champ Davis was also a no show on the depth chart. He missed last week's game against Iowa State after suffering an ankle injury against the Buffalo Bulls.
Bob Sanders is expected to miss his third consecutive game this week after having a cist removed from his foot one day prior to the Buffalo game.
Freshman running back Albert Young may start to practice this week, but his availability for the Arizona State game is highly doubtful.
The injury bug is hitting the Hawkeyes hard this season. Iowa starters missed a total of five games during the 2002 season, which might be the most amazing statistic from that record setting year. This year, Bob Sanders has already missed two starts with a third likely this week, Champ Davis has missed one start and likely a second start this week and now Brown out at least one game.
Iowa lost number two running back Jermelle Lewis in the spring and his return is not likely. Albert Young then moved into the number two spot on the depth chart, but he broke a bone in his leg and has yet to see any action this season.
Iowa head coach Kirk Ferentz will look to even his career record at Iowa against Arizona State. He is 25-26 in four plus seasons as the Hawkeye head man.
With the win against Iowa State, the Hawkeyes are 17-3 over the course of their last 20 games, matching Hayden Fry's best ever 20 game stretch at Iowa.
Iowa has also won 12-straight regular season games, the third best mark in school history.
The Hawkeyes have won 15 of their last 17 home games dating back to the 2000 season and are winners of six straight road games dating back to the 2001 season.
Approximately 5,000 tickets remain for the Arizona State contest.
Sean Considine tied a school record after recording two blocked punts against Iowa State. Considine also blocked two punts during the 2002 season. The record for a single season is three and the career mark is seven.
On another note, the Hawkeyes are well represented in the NFL this season. Iowa ranks fourth in the Big Ten with 20 former Hawkeyes on NFL rosters. Michigan (31) ranked first, followed by Ohio State (29) and Penn State (28). Illinois and Wisconsin tie the Hawkeyes with 20 each. Other national notable teams with former players in the NFL include Arizona State (22), USC (20), West Virginia (20), Washington (20), Texas (19), Oklahoma (16), Virginia Tech (16) and Pittsburgh (12).
