Sean Mannion injury: Oregon State loses starting QB for undetermined period

Sophomore Mannion is completing 63.3 percent of his passes and has thrown seven touchdowns to just four interceptions in four games this season. He will return to an Oregon State passing attack that is averaging 310.7 yards per game, which ranks 14th nationally.

At 6-0 overall and 4-0 in the conference, Oregon State is tied with Oregon for first place in the Pac-12 North division standings. The Beavers will host the Ducks at home on November 24.

Mannion told reporters that there’s no quarterback controversy between he and Voz and that two are completely supportive of one another. Kickoff for the Beavers and Utes is set for Saturday at 7:30 p.m. PT from Reser Stadium in Corvalis, Ore.

SB Nation’s Pac-12 blog, Pacific Takes, also weighed in on Twitter: “Yeah, this is not the week Oregon State wants to lose Sean Mannion.”

It’s a devastating blow to a Beavers team that had plenty of momentum after a 19-6 win over Washington. They are 4-0 and lead the Pac-12 Conference in the standings. They will next face BYU on Oct. 13 on the road.

A three-star recruit out of Stockton, California, Vaz impressed in fall camp, going 12 of 13 for 127 yards and two touchdowns in the last scrimmage. From Building the Dam’s report:

Vaz also looked the best out of all OSU’s quarterbacks at their spring game this year, during which he went 11 of 21 attempts for 2 touchdowns and a pick.

Junior Cody Vaz is listed as next on the depth chart for OSU. (Head here for more on Cody Vaz.) He backed up Ryan Katz last year, picking up 17 attempts worth of game experience along the way.

Oregon State has started the season 4-0, winning its first three conference games to climb up to No. 10 in the AP Top 25 Week 6 rankings.
