It's all or nothing for injured Oregon running back De'Anthony Thomas, who said Wednesday he would be either playing at 100 percent against Washington or not playing at all.
Based on what Thomas told the school's official website, the latter seems to be the more likely result at the moment.
"I haven't practiced this week, but I've been in drills and stuff like that," Thomas told GoDucks.com. "Just getting better, trying to jog a little bit and stuff like that."
Thomas suffered a sprained ankle returning the opening kickoff in the Ducks' Sept. 28 win over California and missed last week's game at Colorado.
Things we learned in Week 6
From Marcus Mariota's seven-TD performance to freshman Jameis Winston's KO of Maryland, here are 40 things we learned about Week 6 in college football. **More ...**
Sophomore Byron Marshall and true freshman Thomas Tyner have been the primary ball carriers in Thomas' absence, combining for 376 yards and four touchdowns on 65 carries in those two games.
Head coach Mark Helfrich gave the running game without Thomas a marginal endorsement on the Pac-12 weekly teleconference Tuesday.
"We've done some good things and we've done some things that we can improve upon both at the running back position and also up front. We can recognize things better, we can block better, we can finish better. A solid okay," Helfrich said.
Marshall has been solid but not spectacular, while Tyner has shown flashes of his tremendous potential, but neither has been the game-changing force Thomas has proven to be in his three seasons at Oregon.
Thomas has 338 rushing yards and six touchdowns in four games and is averaging 8 yards per carry this season. If Thomas somehow does play against UW, his biggest impact could come on special teams.
Ty Montgomery of Stanford scored on a 99-yard kick return against UW and had a 68-yard return to set up another Cardinal touchdown.
Thomas has averaged 26.1 yards per kick return in his college career with three touchdowns.
