Barkley is progressing well from his hamstring injury – but the Villa loanee will not make it back in time for this weekend's derby with Wolves.
Villa boss Dean Smith said: “With the postponement of the Newcastle game, it's one less game for him to miss.
"His recovery is going well so hopefully he will be back, not for the Wolves game, but some time just after that. We don't have to push him so quickly, that's for sure."
Meanwhile, long-term injury absentees Wesley and Tom Heaton are also working their way back after both being out for almost a year.
