STANFORD — There won’t be any mystery this week about who will take snaps for Stanford when it hosts No. 9 Washington.

“K.J. Costello will start again this week,” Stanford coach David Shaw announced Monday.

Costello struggled in Saturday’s 24-21 loss at Washington State under snow conditions, finishing 9-of-20 for 105 yards with no touchdowns and a late interception.

“It’s hard to get thrown in in a game like that, in the weather, against a team like that,” Shaw said. “That’s tough duty, and tough duty again this week.”

Costello scrambled for a 14-yard touchdown run midway through the third quarter, but the offense failed to produce a first down on its final four possessions. Stanford finished with fewer than 200 yards offense.

“I take full responsibility,” Shaw said, repeating what he’d said after the game. “It was not a good game by me. Not good. I have all the excuses, which I hate to hear from other people. I hate excuses. … But the bottom line is we’ve got to do a better job of mixing it up.

“Now, week-to-week, it’s a completely different week. I’m not going to overreact and do something different against Washington that we shouldn’t do.”

Stanford (6-3, 5-2 Pac-12) fell out of the Top 25 for the second time this season and will have its hands full after a short week of practice against the Huskies (8-1, 5-1).

“It’s the best team in the conference coming to our house, so we don’t have time to wallow, to lament about what happened last Saturday,” Shaw said. “We’ve got to get ready to go.”

On the injury front, running back Bryce Love, who was bottled up Saturday except for a 52-yard touchdown run — his other 15 carries produced 17 yards — avoided any serious setbacks after missing the previous week because of an ankle injury.

“Bryce Love came out of the game OK,” Shaw said. “Still not 100 percent, but did well in the game. Had the great breakaway run. Will continue to rehab him this week and try to get him ready for Friday night.”

But the Cardinal won’t have left tackle Walker Little available for the foreseeable future. The redshirt freshman got hurt against Washington State and was replaced by Devery Hamilton, who will fill in for the time being.

“That will be kind of a week-to-week deal, but he’ll be out this week and most likely next week,” Shaw said.

To account for any other bumps and bruises, practice time will be shortened this week in preparation for the 7:30 p.m. kickoff on Friday.

“It’s a lot less, in particular this late in the season, where guys are a little beaten up and you’re taking away one day of recovery,” Shaw said. “We’re all about recovery. We have to get our legs back in seven days, but now it’s six days. So our typical two-hour practices will be 90 minutes the next two days.”
