The Oregon Ducks opened up Pac-12 play Sept. 28 against the California Golden Bears, but the opening kickoff of the game resulted in a possible devastating injury.

Superstar running back De'Anthony Thomas sustained a huge hit on his first touch and came up limping on his left leg, per Andrew Greif of The Oregonian:

Thomas was ruled out for the Ducks' matchup vs. Colorado on Oct. 5. He did not play vs. Washington after being a game-time decision. However, Thomas says he will play this coming weekend vs. UCLA.

From The Oregonian's Andrew Greif:

Thomas didn't play in the second half vs. UCLA. The Oregonian's Rob Moseley gives details:

Thomas spoke about his ankle injury (via Associated Press):

While second-ranked Oregon's coaches never talk about injuries as a strict policy, Thomas was frank about his situation even though he didn't have an exact diagnosis. All he knew for certain was that it hurt enough that he couldn't return against the Golden Bears.

As for next week's game at Colorado, Thomas would only say, "we'll see."

"I was just trying to make a move and it was slippery out there. I'm very focused and I'll get back out there when I can."

Thomas was scheduled to have X-rays on the ankle Sunday, but he was confident when he spoke after the game that it was not serious.

Original Text

Rob Moseley of GoDucks.com noted how Thomas had a towel over his head on the sideline, perhaps indicating that the electric playmaker won't return to face the Golden Bears:

Thomas entered the game with 338 yards rushing on the season, averaging 8.0 yards per carry and six touchdowns. The 5'9', 175-pound junior is explosive but diminutive in stature, so big hits are a cause for concern.

In spite of that early setback, the Ducks quickly drove down the field and scored on their opening possession, capped off with a 14-yard touchdown scamper by sophomore running back Byron Marshall.

Although the Ducks have the luxury of depth and a stud quarterback in Marcus Mariota, Thomas is a key part of their up-tempo rushing attack, which ranked second in the nation, averaging 355.3 yards per contest entering the game.
