Sourav Ganguly's injury is not "very serious" and he could play the Mumbai Test, says India's physiotherapist Andrew Leipus.

"Nothing was revealed in the bone scan, which is a good thing. It means the injury is not very serious.

"There is fluid accumulated in the hip and we had to go back to the MRI scan earlier to start his medication," he informed on Thursday.

Though the physio was unable to say when exactly India's captain will resume playing, he asserted that the left-hander cannot bat for at least a couple of days.

"It will be only light exercise and some specific gym work. We will have a check up on whether he is responding to medication after a couple of days to know exactly when he will be fit to play," Leipus said.

He clarified that Ganguly does not have to undergo surgery and the injury, he feels, is the extension of the muscle strain he suffered in Bangalore.

Earlier on Thursday morning, the Indian team management, in a statement, said: "It is common for hip joint pathology to produce symptoms of referred pain distally in the groin and thigh.

"He [Ganguly] is receiving medical treatment for this condition and progress will be monitored over the next few days."

Ganguly was ruled out of the on-going third Test after complaining of a thigh strain and underwent a bone scan on Wednesday evening.

He had sustained the injury in Bangalore during the first Test, but played the second Test in Chennai.
