The 49ers are looking into alternative solutions for next week's high school football games at Levi's Stadium.
Though the games haven't been postponed or canceled yet, it's safe to assume the high school doubleheader on Aug. 29 will not happen.
The "Friday Night Lights" doubleheader was scheduled in June to match Wilcox High of Santa Clara against Manteca in early game and fabled De La Salle of Concord against Jesuit of Sacramento in the night camp.
After just three events, including one NFL game on sod that was installed in mid-April at $1.2 billion Levi’s Stadium, the field is undergoing major repair.
The stadium’s heavy-traffic area of grass, stretching from sideline to sideline and goal line to goal line was torn out and replaced with a thicker cut of Bandera Bermuda -- selected for its ability to hold up under frequent usage.
Harbaugh pulled his team off the field after less than an hour of Wednesday's practice due to bad field conditions.
"Just felt like there was too much slipping going on," Harbaugh said. "As it relates to the field, the action has been taken. We're refitting, regrouping, retooling, and a new field is going in. Once again, it's our organization, we always count on them to do things at the highest level. And that's what's in process now."
Wide receiver Stevie Johnson aggravated a pre-existing condition when he slipped during Wednesday's practice, Harbaugh said. But Johnson told Harbaugh he will be ready to practice on Friday.
The 49ers have assured the field will be “fine” when the Chargers visit for their third exhibition this Sunday.

In addition to the prep football games, Mexico and Chile are set to have an international soccer match on the field on Sept. 6.
It is not uncommon for entire football fields to be replaced on short notice. In January, the BCS Championship Game took place on an entirely new natural grass field in Pasadena just five days after the Rose Bowl was played.
