Michigan State will be without middle linebacker Max Bullough in the Rose Bowl, but defensive coordinator Pat Narduzzi is eager to see who steps up in his place.
Bullough was suspended for Wednesday's game against Stanford for violating unspecified team rules.
Senior Kyler Elsworth and sophomore Darien Harris are expected to play in Bullough's place.
Michigan State is ranked first nationally in defense, giving up 248.2 yards a game.
"I've seen what No. 40 [Bullough] has done for years and I don't remember the last game we had a different [middle linebacker] in there," Narduzzi said Friday. "But I'm anxious to see what someone else can do at that position."
Narduzzi, who won the Frank Broyles Award as the top assistant coach in college football, said the starter had not yet been determined.
"Flip a coin on Wednesday," he said. "I'm fine with that."
