Utley, who played his fifth Spring Training game as a designated hitter on Thursday, sprained his right ankle in January, and it has been slow to heal.
Outfielder and non-roster invitee Jeff Francoeur has not played since last week because of a sore left oblique. He needs to get on the field if he expects to make the team.
Sandberg said Francoeur, who is hitting .278 (5-for-18) with two doubles and two RBIs this spring, could play in a game this weekend.
"He needs a couple of days of batting practice and then just build up to a game-speed situation for him," Sandberg said. "And him being a high-intensity guy, it might be tough for him to do, but he's going to have to manage a little bit in his first couple of games back by cutting down his swing a little bit and kind of ease into it to see where he's at."
