Smith has been playing with a torn ligament in his right wrist since the Sept. 19 game against Northern Illinois.

Recovery time is 3-4 months. He'll participate in Spring practice, but in a limited capacity.

Meanwhile, Kerrigan broke the fifth metatarsal in his left foot at the end of Saturday's 38-21 victory over Indiana.

Expected to participate in winter conditioning and be 100% by Spring ball.
