Even with a few extra days to prepare for the Arizona State game Thursday night, Stanford’s health doesn’t appear to be much improved.

Both tailback Bryce Love and right guard Nate Herbig are questionable, head coach David Shaw said Monday.

Because of the left ankle injury that kept Love out of the Utah game, Shaw said he was not as hopeful of the All-America tailback’s availability as he was late last week.

“I’m still confident that we’re going to have a chance to have him on the field,” Shaw said.

If Love can’t play, it would be the third game he has missed this season, and presumably Trevor Speights or Cameron Scarlett would start in his place. Love rushed for a school-record 301 yards and three touchdowns against ASU last year in a 34-24 win.

Herbig — probably the team’s best offensive lineman — did not practice Monday because of an undisclosed injury. Devery Hamilton, who played just four snaps against Utah on Oct. 6, is “finally completely healthy,” Shaw said. He and Drew Dalman probably would share the load at right guard if Herbig can’t play.

On the other hand, starting outside linebacker Casey Toohill, who has missed the past three games with an arm injury, will be back for the game at Sun Devil Stadium, Shaw said.

Jordan Fox and Gabe Reid have played well in Toohill’s place, but it will be good to get a fifth-year player back on the field, Shaw said. “He’s excited and fired up and ready to play.”

The Cardinal (4-2, 2-1 Pac-12) are desperate for a win after consecutive losses to Notre Dame and Utah.

“The most bothersome thing to me is, not only have we not reached our potential, we haven’t approached it,” Shaw said. “We haven’t put a complete game together, let alone a three- or four-game span where we’re playing at our best.”

Shaw said it’s up to him to “poke and prod” his team into that type of consistency. “There’s so much more within us than we’re showing on game day.”

It’s vexing to Shaw that his team has been plagued by molasses-slow starts — down 24-7 to Oregon, 14-7 to Notre Dame and 21-0 and 24-7 to Utah.

“We can’t start playing when we’re down seven or down 14, and then play our best football just to get back in the game,” he said.

During the bye week, he said, the top priority was “rest and recovery. We’ve lost two games in a row and haven’t played great yet.” His main concerns remain getting the running game going and stopping the run. “That’s where winning football is,” he said.

Like Stanford, the Sun Devils (3-3, 1-2) are coming off a bye week.

They have been surprisingly strong, especially at home, under first-year head coach Herm Edwards. They beat then-No. 15 Michigan State 16-13 in Tempe, where they also chalked up one-sided victories over Texas-San Antonio and Oregon State.

On the road, they had seven-point losses to San Diego State, Washington and Colorado.

Briefly: The Washington State game at Stanford Stadium will start at 4 p.m. Oct. 27 and be shown on Pac-12 Networks. … Stanford has won five of its past six meetings with ASU, but the Sun Devils have won five of the past seven games with the Cardinal in Tempe.
