Kody Spano's spring practice-ending knee injury will reduce Nebraska's depth at the position to three quarterbacks for the rest of the spring.
Spano, a redshirt freshman from Stephenville, Texas, was a scout-team quarterback last season after arriving early at college last spring. But the departure of Joe Ganz had thrust Spano into a tight battle for the No. 1 job this spring along with Zac Lee, incoming freshman Cody Green and converted linebacker Latravis Washington.
It will mean a lot more throws for those remaining quarterbacks during the rest of spring practice, which will end Saturday with the Red-White game.
But Spano's injury, coupled with the earlier departure of expected challenger Patrick Witt, throws the position into flux for the next few months.
It remains unseen if coach Bo Pelini will attempt to convince a junior-college player to transfer into the program to provide more depth at the position.
A more likely scenario will be that Taylor Martinez, a heralded high school quarterback from Corona, Calif., who had been ticketed to play defensive back, might receive an immediate shot at quarterback when he arrives this summer.
And it also would make a chance to play for the Cornhuskers that much more enticing for former Miami quarterback Robert Marve, who is expected to attend Nebraska's spring game on Saturday during his tour of potential schools.
