"In my own mind, you think about those things, but really I haven't gotten to that point," Gonzalez said. "I think there's some logistics contractual things and that sort of stuff that they might not be able to do it that easy."
Upton was not available for comment before Atlanta hosted the Washington Nationals.
Gonzalez has spoken with Upton about his absence from the lineup, but not about an assignment in the minors.
"He understands to a certain point," Gonzalez said. "Like good players do, they want to play. We've had conversations and he's making the adjustments and we'll see."
Upton is hitless in the Braves' past seven games. He was out of the lineup Friday for the second straight night.
