Steven Finn has been ruled out of England's second Test against India in Mumbai by a thigh injury.
England coach Andy Flower revealed that the Middlesex paceman faces a second scan on Wednesday to assess the injury.
England will be without Ian Bell as they bid to bounce back from their first Test defeat in Ahmedabad as he has already returned home for the birth of his first child.
If the scan shows no major problem, he will be considered for an England Performance Programme match - with a view to returning in time for the final two Tests in Kolkata and Nagpur.
"Steven has been working hard to get back to full fitness," said Flower. "He has unfortunately hurt his leg again, a couple of days ago, and is having another scan tomorrow.
"We don't think he's got any structural damage, but it would be careless to suggest that he might play the second Test."
England will tread carefully with Finn, but remain optimistic.
"What we might do is send him off to the performance programme that arrived in India earlier this morning," added Flower. "They've got a three-day game starting on the 27th. If he's ready for that, which is the last day of the second Test, we'll put him through his paces in that.
"If he comes through that well, he'll be available for the third and fourth Tests."
Bell, meanwhile, is celebrating the birth of son Joseph William. Bell's wife Chantal gave birth on Monday, shortly before Bell arrived back in England despite leaving the first Test early once it became clear his son was on the way.
