The Norwegian striker has been out for the last two months with the problems but will now be hopeful of a first team return in the next few weeks.
Villa have been on a great run since Carew's injury and he may actually struggle to get back into the side.
Martin O'Neill has employed Gabby Agbonlahor up front in a lone striker role with Ashley Young and James Milner supporting the speedy starlet.
And it has paid dividends with Villa remaining unbeaten for their last ten league games. During that time the Claret and Blue have secured great wins at Everton, West Ham and Arsenal.
As well as they have done, Villa know that Carew's presence adds options up front. The team have struggled in games at Villa Park without the extra dimension that the Norwegian provides.
Other news on the injury front is not so good for O'Neill. Martin Laursen aggravated his knee injury against West Brom and could be out for a prolonged spell.
The Danish centre back missed the wondrous win at Sunderland and O'Neill says he is not sure how long his influential captain will be out for.
Carlos Cuellar will be required to stand in just as he did at the Stadium of Light on Saturday.
With Ashley Young banned for the next three games after being sent off against the Black Cats, Villa could really use Carew and co back sooner rather than later.
