Petrov has returned to full training after sitting out the 1-0 Premier League home defeat by Liverpool at the weekend.
It could mean manager Owen Coyle facing a decision whether to keep Matt Taylor in the team or recall the Bulgarian.
Meanwhile, Coyle insists he is always willing to talk to frustrated players.
"My door is always open, so it never gets a bashing," he said.
"Anybody can come and have a chat. I think that's healthy, important. That's the way I work."
