STANFORD, Calif. -- Stanford starting quarterback Keller Chryst is expected to be back in action during fall camp, coach David Shaw said.

"Keller is right on schedule to be back full-go for training camp," Shaw said. "Hopefully we won't have any setbacks between now and then."

Stanford has not disclosed Chryst's exact injury, but he did hurt his knee during the Cardinal's win over North Carolina in the Hyundai Sun Bowl. During a press conference on national signing day last month, Shaw expressed uncertainty about Chryst's availability for camp, but this week he indicated that Chryst underwent successful surgery and is now in the rehabilitation process.

"We won't rush it," Shaw said. "If he's not 100 percent at the beginning of training camp, that's fine. We're not going to hit the panic button. He's doing really well. As of right now, we're gearing toward him participating relatively early, if not day one of training camp."

The Cardinal began spring practice this week with only two active scholarship quarterbacks on the roster. Ryan Burns, who began last season as the starter before being unseated by Chryst, and K.J. Costello are currently splitting repetitions.

ESPN 300 prospect Davis Mills will also join the fray when he enrolls at Stanford this summer.

Chryst threw for 905 yards, 10 touchdowns and two interceptions in 2016. The Cardinal went 6-0 in his starts, and Shaw has indicated that the 2017 starting job is Chryst's to lose if he is healthy by the time the season rolls around.
