Stanford will open training camp next week in better shape at quarterback than it was at the close of spring practice.

Presumptive starter K.J. Costello and backup Davis Mills could be limited, to differing degrees, for the early weeks of camp. According to coach David Shaw, Costello, at least, will be ready for the season opener.

Costello missed spring practice with a hip injury, while Mills didn’t participate because of ligament damage in his knee.

Without them, former walk-on Jack Richardson ran the Cardinal offense; Richardson was placed on scholarship at the close of spring and is healthy for training cam, which begins Wednesday.

Shaw indicated that Costello’s recovery is further along than Mills’.

Stanford opens the season Aug. 31 against San Diego State.

The Cardinal was picked second in the North in the preseason media poll. Cal was picked fourth.
