Gonzalez left Thursday's game against the Giants after tearing a ligament in his left ankle stepping awkwardly on first base. The injury was first thought to be season-ending.
Gonzalez remains in a protective boot, but interim manager Tony DeFrancesco anticipates a return to the lineup this season.
"We don't need to put him on the DL," DeFrancesco said.
No timetable has been set for a return.
"We don't know how long it's going to be," DeFrancesco said.
