Starter Keith Price suffered a knee injury against USC last weekend. While there is no structural damage, according to Sarkisian, Price was unable to practice this week.
Sarkisian's Tweet is a course reversal. He said after practice on Wednesday night that he wouldn't publicly announce the starter, but would let the team know.
Montana was 9 of 15 for 73 yards and threw a 20-yard touchdown pass to Kasen Williams in relief of Price last week against the Trojans. For the season, Montana is 13 of 20 for 147 yards with one touchdown and one interception.
Considering that Oregon State has the No. 11 run defense in the Pac-12, you can bet that Huskies running back Chris Polk will get plenty of touches, particularly if its cold and rainy in Corvallis, as expected.
