LINCOLN, Neb. (AP) — Nebraska quarterback Taylor Martinez missed practice Tuesday, putting his availability for Saturday’s game against South Dakota State in question.

Coach Bo Pelini said Martinez was wearing a walking boot on his left foot the last two days because of turf toe.

Senior Ron Kellogg III or redshirt freshman Tommy Armstrong Jr. would start against the Jackrabbits if Martinez can’t play.

Pelini said Martinez will play if he’s healthy but “we’re going to make sure he’s 100 percent and feeling good.”
