With three of their last four wins coming on the road, Riley said he worries his team might be set up for a letdown against the Utes now that they'll be back in their own stadium.
Those wins were tough games, he said, and the Beavers should expect another one from the Utes.
"I always warn our team it is a trap you can fall into if you think something different is going to happen, and you can't do that," he said.
So far, the Beavers haven't shown any indication of letting up.
"I worry a lot about that, but so far I don't see anything from our team that makes it real," he said. "This team's demeanor yesterday was good, efficient and a relatively quiet practice. I'm impressed with their attitude and work ethic. I don't even know if they know what they've done to this point. They just get ready to play."
No Oregon State team has started 6-0.
Back at it
Former Utah quarterback Jordan Wynn watched practice from the sideline Tuesday. Wynn had shoulder surgery last week.
"It went well," he said. "Last surgery. I don't know what all they did, but they cleaned a lot up."
Also watching practice was former quarterback Terrance Cain.
Game time set
Kickoff for Utah's home game against Cal on Oct. 27 has been set for 7:45 p.m., and will be televised by the Pac-12 Networks.
