Stoke City manager Mark Hughes says Joe Allen was “compromised” on Wales duty after he picked up a hamstring injury in their draw against Austria.
The Potters midfielder scored in the 2-2 draw on 6 October but came off after the break in Vienna.
Allen was ruled out of Sunday’s 1-1 draw against Georgia after scans showed the extent of the injury.
“We’re still checking on Joe, he hasn’t trained with the group yet,” the former Wales manager said.
“We would have given him an extra day’s rest but he trained with Wales and that’s probably compromised him a little bit so they have to be a little bit careful in that regard.”
Hughes’ side face Sunderland at home on Saturday, hoping to pick up their first win in the Premier League this season, but the Stoke boss hopes the summer signing from Liverpool will be fit to feature against the Black Cats.
“We’ve just got to be a little bit careful with him; unfortunately he probably did a little bit too much with the Welsh squad,” Hughes said.
“We’re hopeful that he’s going to be OK and we’ll have to check on him tomorrow.”
The Football Association of Wales declined to comment when contacted by BBC Wales Sport.
