Marcus Mariota insists his left knee isn't a concern and that he'll be ready to go Saturday when No. 6 Oregon hosts Utah.
There are lingering questions about how much the mysterious knee injury contributed to the Ducks' loss at Stanford last Thursday. Oregon doesn't discuss injuries, and the sophomore quarterback hasn't been specific about what's going on.
Asked this week whether his knee is an issue, Mariota said it wasn't. Pressed whether he is 100 percent, Mariota said he couldn't say.
Mariota remains a Heisman Trophy hopeful with a stellar season thus far. He's completed 63.3 percent of his passes for 22 touchdowns with no interceptions. And he's ranked second on the team with 495 yards rushing, with nine additional TDs.
