Spence did not accompany No. 7 Ohio State on its trip to the bowl, with the team citing “a personal issue.”
The Buckeyes (12-1) play No. 12 Clemson (10-2).
As recently as Monday, the team said there was some hope that Spence – an All-Big Ten player this season – would be able to join the team for the game.
Spence also will sit out the first two games of the 2014 season, the team said.
Spence led the Buckeyes with eight sacks this season. He also had 14½ tackles for loss, second-most on the team, and had 52 tackles.
LOUISVILLE: Quarterback Teddy Bridgewater will forgo his senior season with the No. 18 Cardinals and enter the NFL Draft.
Projected as a first-round selection and possibly the first QB taken this spring, Bridgewater completed 71 percent of passes for 3,970 yards and a school-record 31 touchdowns this season.
He closed out his time at Louisville with a career-best 447 yards with three touchdowns in Saturday’s 36-9 rout of Miami in the Russell Athletic Bowl.
MICHIGAN STATE: Mark Dantonio has agreed to a new contract with the Spartans that will make him one of the three highest-paid coaches in the Big Ten.
It will also place his assistants among the three highest-paid staffs in the conference, according to ESPN.com.
Dantonio’s salary had been in the bottom third of the conference.
The raises came before the No. 4 Spartans (13-1) beat No. 5 Stanford (12-2) 24-20 in the Rose Bowl on Wednesday.
It was Michigan State’s first appearance in the game in 26 seasons.
Dantonio, 57, is 63-29 with Michigan State in seven seasons. And consistent with the stability he has built for the program, Dantonio wanted to keep his entire staff together.

It was the only catch of the game for Rice.
Rice ended his career with 11 catches for 86 yards, all this season.
