The Cougars' star had been unable to start the game due to a stomach virus, but entered the midway through the first quarter.
Bud Withers of The Seattle Times described the scene:
Tuel threw only two passes on his drive for a field goal, but it may have been a scramble that cost him the collarbone. On a 2nd-and-6 play at the Idaho State 10, he looked for a quick shot over the middle, didn't see anything and ran to his right. He was flipped down at the right sideline, but got up quickly and didn't appear to be hurt.
Stopped for no gain on the play, Tuel then threw a four-yard flip to Rickey Galvin before a WSU field goal made it 17-0.
Tuel, NFLDraftScout.com's No. 6 rated quarterback for the 2013 draft, entered the season as a favorite breakout candidate for many. The 6-3, 223 pound junior completed 59.8% of his passes for 2,780 yards and 18 touchdowns playing behind a porous offensive line. He plays in a spread offense, but has the mobility to handle the conversion to a pro-style offense. Tuel has the arm strength to make every NFL throw and shows great touch on deep balls. Perhaps most intriguing, Tuel has played well when pitted against top competition. I scouted Washington State against Stanford (Andrew Luck), USC (Matt Barkley) and Washington (Jake Locker) and left feeling that Tuel had made some of the best passes in each contest.
Until more tests are run, the length of time that Tuel will be sidelined isn't known. Withers offered a "rough guess" of 6-8 weeks, citing the normal timetable of most similar injuries.
The injury is a cruel one for the Cougars. Their head coach, Paul Wulff, is 5-32 in his first three seasons and is widely rumored to need a successful fourth season to avoid losing his job. Though the improvements in this team haven't yet translated into victories, Wulff and his staff inherited a pretty bare cabinet of talent and have rebuilt the program into one entering this season with quiet confidence that a bowl game was possible.
Even with the loss of their best player, the Cougars improved depth was obvious in their rout of Idaho State. (WSU ahead 61-20 in third quarter as of 7:45 pm ET). If there is a silver lining for Washington State, it is that they start their conference schedule against UCLA and Colorado, potentially two of the more winnable Pac-12 games.
