San Jose State sophomore linebacker Derek Muaava's season is over after an MRI revealed a torn anterior cruciate ligament in his right knee.
He was injured while covering a punt return in the Spartans' 31-20 win over Texas State last weekend.
"That's a tough loss," coach Mike MacIntyre said. "He's a physical presence."
Muaava was a starting outside linebacker. He'll be replaced in the lineup by redshirt freshman Hector Roach.
Also, cornerback Damon Ogburn Jr. (hamstring) returned to practice after missing the past two games and will be available at Idaho on Saturday. Before his injury, Ogburn was a starter at cornerback and an ace special teams player.
