"We are pretty confident Bacarri will (play)," Richt said. "We are a little less confident that A.J. will, but we're not counting him out yet."
Green, Georgia's leading receiver, suffered a left shoulder sprain after being tackled against Auburn. Richt said Green still does not have full range of motion in the shoulder, which doesn't bode well for his immediate return.
"Right now we're still working on the strength and getting the soreness out," Richt said. "He doesn't have full range of motion right now, but sometimes those things can change quickly and sometimes they don't."
Richt said Green would likely need to have seen dramatic improvement by Thursday in order to play against Tech.
Offensive coordinator Mike Bobo said he would hold out hope right up until kickoff, however, that Green might be able to play.
"I'm approaching it that I hope he's out there. I'm still optimistic," Bobo said. "I think he could go out there if he's ready to go gametime, we could tell him what to do and he could go run the route and make some plays."
If Green misses the game, freshman Rantavious Wooten would likely get the start in his place.
