Northwestern has issued its official injury report for Saturday's home opener against Illinois State.
Safety David Arnold, foot
Linebacker Roderick Goodlow, knee (ACL, out for season)
Guard Keegan Grant, illness
Wide receiver Tony Jones, shoulder
Defensive tackle Niko Mafuli, knee
Linebacker Tim Riley, shoulder
Linebacker Bryce McNaul, shoulder
Mafuli, the team's No. 3 defensive tackle, sustained the injury last week at Vanderbilt and will be replaced by Will Hampton. McNaul actually has been upgraded after being listed as out on the Week 1 injury report. He should be back for Big Ten play, if not sooner, although his injury history is a concern. Northwestern also would like to get Arnold back on the field, as the depth situation at safety isn't great.
