Cricket icon Mahendra Singh Dhoni's mentor Deval Sahay, who was hospitalised in a Ranchi hospital on Tuesday with multiple ailments including breathing problems, continued to show improvement on Monday, and is now completely off ventilator support.

"Deval was off ventilator on Sunday till noon. After that his Co2 level started rising. So, they had to give Oxygen by non-invasive method - BIPap. He is improving but it will take time because his lung muscles are little weak and Co2 is not being expelled," said Sahay's wife Meena told IANS.
