Simmons has been on the 15-day disabled list since breaking his right pinkie finger July 8 in the Braves' 4-3 victory in Philadelphia on the final day before the All-Star break. He has begun therapy and is hopeful he will soon be cleared to begin baseball activities.
Simmons said his hand feels fine.
"I can pretty much do everything with it," Simmons said. "It's still a bit sore. I have to stretch it out a bit still, but it feels great."
Manager Fredi Gonzalez said shortstop Jack Wilson, outfielder Matt Diaz and catching prospect Christian Bethancourt were all scheduled to see Lourie as well.
Wilson is back in Atlanta after suffering another setback in his rehab with Triple-A Gwinnett. Wilson has been on the 15-day disabled list since July 14 with a dislocated right pinkie finger.
Diaz has been on the 15-day disabled list since July 21 with a right thumb bruise. Betancourt, who entered the season ranked as the Braves' No. 3 prospect and has been at Double-A Mississippi all season, broke his left hand Aug. 9 when he was hit by a pitch and is out for the year.
