Grealish has missed the club’s last three matches, including league defeats to Liverpool and Wolves, with a calf injury sustained at Manchester City last month.
Matt Targett is also pencilled in for a return to training this week, though the full-back will be monitored under the FA’s return to play protocols after being forced off at Molineux on Sunday with concussion.
Boss Dean Smith, meanwhile, remains hopeful goalkeeper Tom Heaton and defender Bjorn Engels will be back available for the visit of the Magpies a week on Monday.
There is, as yet, no timescale on the return of Jed Steer. The 27-year-old has seen a specialist to determine the best way to treat the calf injury which saw him forced off after just eight minutes at Wolves, having replaced Heaton in goal.
