A series of tweets less than an hour before kickoff indicate that Ohio State will be without wide receiver Austin Mack and defensive end Jonathon Cooper.

Both Mack and Cooper were considered game-time decisions heading into the matchup against Wisconsin in Week 9.

Mack has 15 receptions for 207 yards and two touchdowns in seven games this season. He missed four regular season games last year because of a left foot injury, but it’s unclear at this time what he’s dealing with this Saturday.

Cooper’s injury is also disclosed. If both don’t play, it will be the first time this season either is missing a game.

Ohio State hosts Wisconsin in a battle of Top 15 teams at Ohio Stadium on Saturday at 12 pm ET.
