Iowa running back Fred Russell is doubtful for Saturday’s game at home against Wisconsin. Russell injured his hand in Saturday’s win over Michigan but coach Kirk Ferentz says it is not fractured, but it was jammed pretty good and Russell will be day-to-day.Ferentz says he is leaving the door open for running back Aaron Greving to return to the team. The Ames native left the squad last Thursday during an injury plagued season in which he opened fall practice as the starting running back. He says Greving’s situation gives people not involved in athletics insight into how tough it is for players to deal with injuries. Ferentz says the while the Hawkeyes were impressive in the victory at Michigan, Ferentz says any letdown would result in a loss to the Badgers.Iowa State coach Dan McCarney says he has not lost confidence in kicker Adam Benike. The Cyclones are coming off a 21-10 loss at seventh-ranbked Texas, a game in which Benike missed two short field goal attempts. McCarney says he told Benike he’s the guy and has done a great job so far, even though Saturday was disappointing.The Cyclones have lost two straight games and McCarney says while they are disappointed they are not discouraged. He says they’ve lost all three of their games to highly ranked teams and are ready to enter the month of November with a lot to play for.McCarney hopes the Cyclones take the same amount of confidence out of the Texas game that they got in the season opening loss to Florida State. He says they gave a tremendous effort and just came up short.
