>>Illini RB Ferguson Doubtful For Saturday vs No. 22 Iowa

Interim Illinois coach Bill Cubit says he doubts injured running back Josh Ferguson will be able to play Saturday against No. 22 Iowa.

Cubit said Monday that the starting back was due to see a doctor later Monday. But Cubit said that he wasn't optimistic the right-shoulder injury would allow Ferguson to play.

Illinois (4-1, 1-0 Big Ten) lost Ferguson in the first quarter of last Saturday's 14-13 win over Nebraska. The senior has 397 yards and three touchdowns on 71 carries.

Freshman Ke'Shawn Vaughn took over for him Saturday and was the only other Illini back to carry the ball. Vaughn had 98 yards on 24 carries.

Cubit said Illinois will need little-used junior Henry Enyenihi to help pick up the rushing load at Iowa (5-0, 1-0).

>>Group Says Officials Made Mistake in Illinois Game

The Big Ten officials' organization says a third-quarter officiating mistake cost Illinois a down in its 14-13 win Saturday over Nebraska.

Collegiate Officiating Consortium Coordinator of Officials Bill Carollo said Monday that replay officials should have given Illinois another down when they reviewed a situation in which field officials lost track of the down and distance.

Instead the play that Illinois thought was third down was judged to be fourth down. Illinois had to turn over the ball at its own 44-yard line.

Carollo said "errors of this nature have a significant impact on game assignments, bowl assignments and overall year end status."

Illinois defensive end Dawuane Smoot said Monday the mistake motivated the crowd and defense.
