It's duck and cover for Oregon quarterbacks

EUGENE, Ore. -- An overstuffed couch. A cool, dark room with the shades drawn. And the door locked.

Who could blame the Oregon quarterbacks for wanting a safe place to spend the remainder of the football season?

The No. 23 Ducks arrive at the Coliseum to play ninth-ranked USC Saturday in the midst of an incomprehensible, occasionally surgical, rash of injuries.

Seven quarterbacks knocked out of action in less than a year.

The team's defensive leader, rover Patrick Chung, calls it God's will, as if describing a tsunami. Offensive coordinator Chip Kelly muses, "It's been interesting to say the least."

With starter Nate Costa gone for the season, Oregon is hoping that second-stringer Justin Roper and his injured knee can be ready for Saturday's game.

If not, the Ducks will continue to alternate between third-stringer Jeremiah Masoli, back from a concussion, and a pair of freshmen.

"It's not fair," Masoli said of Oregon's medical misfortunes. "But every team has to deal with injuries."

So far, the Ducks have gone 4-1, and 2-0 in Pacific 10 Conference play, by compensating.

They will attack USC's suddenly questionable defensive front with the backfield tandem of LeGarrette Blount and Jeremiah Johnson, who have combined to rush for 184 yards per game. The return teams have excelled, and the opportunistic defense ranks among the Pac-10 leaders in sacks and interceptions.

"This has been a wake-up call to knuckle down," Chung said. "People had to step up."

But in a conference that lives and dies by the pass, it's hard to look past troubles at quarterback.

For Oregon, the destructive cycle began late last season when Heisman Trophy candidate Dennis Dixon suffered a torn ligament in his knee.

"He was the heart and soul of our team, and it took our guys almost a week to recover," Kelly said. "They realized how much he meant to us."

Oregon, ranked No. 2 at the time, lost three straight games, dropping from the national championship picture.

Adding injury to insult, second-stringer Brady Leaf rolled an ankle and his replacement, Cody Kempt, suffered a concussion as the Ducks finished the season with a variety of backups.

This fall, any hopes of a fresh start lasted only a few weeks into training camp as Costa went down because of a knee injury.

Roper started the opener against Washington and left because of a concussion. He returned for the next two games, then suffered a partially torn ligament in his knee.
