Simmons will begin his rehab stint Monday with Double-A Mississippi in the final game of their season. He will then move to low Class A Rome on Wednesday before heading to high Class A Lynchburg. Rome and Lynchburg will both be playing in the playoffs when Simmons joins them.
Simmons opened the season with Mississippi before getting called up May 31. He played 33 games with Atlanta before he got hurt, hitting .296 with a .452 slugging percentage.
Simmons said he's looking forward to playing one more time with his old teammates.
"See all the guys again, that's really cool," he said. "It'll be fun."
The Braves haven't mapped out exactly when Simmons will return to Atlanta, but manager Fredi Gonzalez said the best-case scenario would be next weekend for the Braves' series against the Mets.
"Hopefully we get at least three games, hopefully they don't get eliminated," Gonzalez said. "If everything looks good, no setbacks, hopefully, maybe next weekend."
Simmons said he understands he has to get game experience after missing two months, but will be ready whenever the Braves give him the call.
"I guess I've got to play to see how I'm doing and what it's like to hit in the game and field ground balls," Simmons said. "I feel like I can play now."
