The Board official said that the initial offer letter has already been sent to the physio, who took charge today, and the details would be sent to him soon.
"We will give him the contract document in the next few days. It will be a one-year contract for the first year," Nair told PTI over phone from Thiruvananthapuram.
Nair said depending on Gloster's performance in the first year, he could be given a longer tenure.
"We will review his performance at the end of the one year period, and then take a decision on extending it or giving him a longer tenure," he said.
Gloster had yesterday said that he was awaiting clarifications on certain terms of the contract, including the tenure.
Gloster, who worked with the Bangladesh national team over the last four years and was instrumental along with coach Dave Whatmore in putting in place a system for them, arrived in Mumbai yesterday on the opening day of the Challenger Seriec.
The BCCI had opted for Gloster, after Andrew Leipus quit as physio of the national squad to pursue his studies further on the subject in Australia.
