It's the second time that Keller has had an injury prematurely
end a season and another blow for a program that has spiraled
downward after reaching the Big 12 championship game last season.
The Cornhuskers (4-5, 1-4 Big 12) have lost four straight for
the first time since 1961 and are 17-point underdogs for this
Saturday's game in Lawrence, Kan.
Callahan didn't specify the type of injury to Keller's shoulder.
Keller was hurt with 2:37 left in Saturday's 28-25 loss at Texas
when he was hit by defensive end Eddie Jones. Keller's left arm was
in a sling as he stood on the sideline near the end of the game.
Callahan also announced that linebacker Lance Brandenburgh
suffered a season-ending shoulder injury against the Longhorns.
Brandenburgh was hurt trying to make a tackle in the fourth
Keller transferred from Arizona State last year, was named
Nebraska's scout team player of the year and then won the starting
job over Ganz in preseason practice. He completed 63.1 percent of
his passes for 2,422 yards and 14 touchdowns. He was intercepted 10
"We couldn't be more pleased with everything he's done for
us," Callahan said during a teleconference with reporters, "just
his ability to come in as a transfer student and be a player who
earned the respect of his teammates.
"He's had ups and downs. I'm appreciative of his efforts. He's
a good kid, a classy individual. He was a real leader for us during
some troubled times.''
Ganz, a junior, has appeared in three games this season. He
completed 2 of 3 passes against Texas, including a 4-yarder for a
touchdown to Maurice Purify. Ganz also converted on a 2-point pass
to Nate Swift.
Ganz's other appearances came in wins over Nevada and Iowa
Ganz's running ability gives the Huskers flexibility in their
offense. He appeared in five games as Zac Taylor's backup last season.
"We've given our backup quite a few [practice] reps during the
season, and he's well-prepared," Callahan said. "He'll give it
his all. He's excited about the opportunity. Our team and staff
have the utmost confidence in him. We lose a good player, but we
have a good player stepping in."
Keller had a college career of great highs and great lows.
He emerged in 2004 at Arizona State, making his first career
start against Purdue in the Sun Bowl. He threw for 370 yards and
three touchdowns and was named the game's most valuable player.
Keller started ASU's first seven games in 2005, throwing for
2,165 yards and 20 touchdowns. He threw for four touchdowns in each
of the first four games, including 400-yard outings against LSU and
But a thumb injury against Oregon ended his season, and he lost
his job to Rudy Carpenter before the 2006 season in a strange
twist. Dirk Koetter, since fired at ASU, named Keller the starter
in preseason camp but changed his mind the next day and announced
he would go with Carpenter.
With one season of eligibility remaining, Keller opted to
transfer to Nebraska, where he toiled on the scout team during the
year he was required to sit out.
"I have respect and admiration for him as a person and
competitor," Callahan said. "This hurts us, but it also creates
an opportunity for Joe Ganz to step up."
