SANTA CLARA -- Coach Jim Harbaugh does not plan to alter the play time for his regulars on Sunday due to concerns over the field conditions at Levi's Stadium, he said Friday.
"I'm sure the field is going be good and playable," Harbaugh said.

The 49ers and San Diego Chargers are scheduled to meet in the third exhibition game for both teams. The third game is generally when teams play their starters the most of any of the exhibition games.
"What's going on is a new grass field is being put down," Harbaugh said. "And it'll be ready for Sunday."
The solution for this weekend's game is temporary. The field will again be ripped up and a new permanent layer of sod will be installed after Sunday, Harbaugh confirmed.
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.
