"It's not worth the risk," Bochy said.
Panik said he will see how his back feels Wednesday and plans to take it day by day.
"It's one of those things that's part of the season; you have to deal with it," Panik said. "Having the off-day definitely will help clear things up."
Bochy characterized Panik's absence as precautionary, but if Panik were to miss an extended period of time, it would be a big blow for a team that has dealt with a plethora of injuries.
Panik is hitting .309 with seven home runs and 34 RBIs in his first full season in the big leagues and leads all National League second basemen with a 3.7 Wins Above Replacement, according to Fangraphs.
