Aston Villa boss Martin O'Neill has been boosted by the news striker Marlon
Harewood's injury is not as serious as first thought.
The former West Ham striker was ruled out of Sunday's 1-0 defeat at Manchester City after pulling up in training on Friday with a knee injury.
Initial examinations suggested the 28-year-old could be out for two months with a stress fracture, but subsequent scans have revealed the injury is far less serious than first feared.
"At the end of training on Friday he pulled up with a problem at the back of the knee. He'd had a bit of discomfort there some weeks ago - at the back end of last season with West Ham - but I think the rest during the summer had allowed it to settle down," O'Neill told the club's official website.
"This is the first time he's complained about it here and as a precaution we sent him for scans. The first one showed a possibility of a stress fracture.
"But after further examinations and the benefits of other scans, we don't think at this minute that the situation is as bad as all that.
"Marlon feels half decent and we are now treating it as a lot of bruising around that area.
"So, though we're still cautious it might not be the length of time out we first feared. That would be great news.
"However long he's out, it's very frustrating for him. He's been absolutely flying in training and he's doing everything he can to make a big impression here.
"We'll have a better idea towards the end of the week, but the feeling now is that he won't be out for too long."
