The 27-year-old defender opened the scoring in the first half of Saturday’s 1-1 FA Cup third round draw at Wycombe Wanderers but was later forced off with an ankle problem eight minutes from the end of the match.
Garde said at the time that he did not know how serious the knock was but now believes his skipper should be available to take on Alan Pardew’s side at Villa Park tomorrow night.
The former Manchester City man started at right-back on Saturday in place of the injured Alan Hutton and is expected to reprise his role against Palace with his fellow defender still sidelined with the hamstring problem he picked in the recent 3-1 defeat at Sunderland.
Carlos Sanchez is also struggling with a similar issue which will keep him out of a third successive match, but Garde thinks the Colombian midfielder should soon be back in contention.
“Alan Hutton and Carlos Sanchez won’t be fit for this game,” Garde told reporters. “Carlos is recovering quite well but he’s not fit yet.
“Micah has a knock on his ankle but should be ok.”

Skipper Richards was seen pleading for calm with fuming fans at the final whistle and it has since been reported that complaints have been made to the club about the veteran duo’s behaviour.
Garde stressed that he was not aware of the incident but did remind his squad of their responsibilities as senior professionals.
Asked if the two players could face any disciplinary action which may lead to them missing the Palace match, the Frenchman said: “I was not aware of the incident because I came back straight away in the tunnel.
“To be fair I don’t know that. What I can say is as a professional player you need to behave in the right way with respect for everybody.
“It doesn’t matter if you are top of the table or bottom of the table. It’s just a question of being respectful to everybody. But to be fair I don’t know exactly this situation."
