Chadli has recorded four goals and two assists in seven Premier League appearances for West Bromwich Albion, but has missed the last two matches with a knee complaint.
"We have one or two knocks," the head coach told wba.co.uk. "We will make a late decision on Chadli. Most of the lads are fine.
"I can't wait to get Nacer back in the team but at the moment I don't think I can get him back in. Everyone has done so well."
