Oregon State announced today that quarterback Sean Mannion sustained a knee injury Saturday against Washington State and will have knee surgery, sidelining him indefinitely.
There’s no immediate word on the damage Mannion sustained, so it’s not known if the injury is season-ending. Replacing him will be junior Cody Vaz, a junior with limited experience. Vaz completed six of 17 pass attempts in 2010 while backing up Ryan Katz.
In the past, OSU coach Mike Riley talked optimistically about Vaz’ future, saying he felt the Beavers had two quarterbacks (including Mannion). Now we’ll find out.
It’s terrible timing for the Beavers, who attained their first top-10 ranking this week since 2001. They go to Brigham Young Saturday, and the Cougars have their own quarterback-knee issues.
Freshman Taysom Hill, who had earlier replaced veteran Riley Nelson, took a hit on a knee in the waning moments of a 6-3 victory over Utah State Friday night, and apparently is out for the OSU game. Nelson, who was the quarterback a year ago when BYU won convincingly in Corvallis, as well as the guy under center in the opening victory of 2012 over Washington State, will get the call. The severity of Hill’s injury is undetermined as of this writing.
Mannion had outperformed every other Pac-12 quarterback before the WSU game in leading the undefeated Beavers. He took a step back, however, with three interceptions and the Cougars frequently pressured him, sacking him three times.
