Nebraska's biggest question heading into the season became a little dicier when coach Bo Pelini announced that backup quarterback Kody Spano will miss the season after re-injuring his left knee.
It means that projected starter Zac Lee's backups at the position are a little thinner after Spano tore the anterior cruciate ligament for the second time in four months.
"I'm not worried about us, I'm worried about him," Pelini told reporters after Nebraska finished its practice on Wednesday. "He worked his tail off to come back and I feel bad for the kid."
Spano had competed with Lee for the starting job before originally injuring his knee in a non-contact drill during the spring. The second injury also happened in a non-contact drill in the Cornhuskers' practice on Tuesday, Pelini said.
This injury is a big loss for the Cornhuskers, considering the lack of experience behind Lee.
It likely means that heralded freshman Cody Green will be ticketed for duty with the team this season and probably has killed any hopes of redshirting him.
The Cornhuskers also have converted linebacker Latravis Washington and freshmen Ron Kellogg Jr. and Taylor Martinez in camp. Kellogg, the son of former Kansas basketball standout Ron Kellogg, will replace Spano on the Cornhuskers' 105-man roster after originally arriving as a walk-on candidate.
An injury to Lee would have catastrophic effects for the Cornhuskers. Their quarterback situation remains the team's biggest concern heading into a season where many observers are picking them to contend for the North Division title.
To get there, the Cornhuskers will need some luck in terms of staying away from injuries -- particularly at quarterback.
