The Bulgaria international has been out with a virus, but is now back in training.
“The virus is okay. It is better,” said Petrov.
“I’ve been on antibiotics for the last three or four days and we are eexpecting every day for it to get better and better.
“I’ve done a bit of training this morning, I am going to train with the team this afternoon as well to try to catch up. I think it should be okay for Sunday.”
