According to sources, Dhawan has some 'issues' on his left thumb that had sustained a minor fracture after the second Test versus New Zealand in October.
"He went to consult in the radiology department and was there for more than an hour," a local official said.
Having failed in both the ODIs with scores of 1 and 11, Dhawan's spot is already in question with likes of Ajinkya Rahane warming the bench.
Meanwhile, former India captain and Cricket Association of Bengal president Sourav Ganguly has promised a sporting wicket for the final one-dayer.

"It will be a good wicket we hope to see a perfect cricket match," Ganguly said.
The one-day action will return to the Eden after two years with Rohit Sharma's world record 264 fresh in the memory.
Sharma's epic knock powered India to 404/5 in the last ODI here as India beat Sri Lanka by 153 runs on November 13, 2014.
