British orthopaedic surgeon and knee specialist Dr Andrew Williams, who had worked with the likes of Andrew Flintoff, Shoaib Akhtar, and more recently Cheteshwar Pujara, is likely to operate him August 7.
"I'm returning on August 16 and thereafter will go for rehab at NCA (Bangalore)," Tiwary said while felicitating U-17 cricketers of Mainland Sambaran Cricket Academy who won CAB Junior Tournament.
The Bengal skipper has been ruled out for about six months as he is set to miss out on the initial stages of the Ranji Trophy.
Asked about his spate of injuries, Tiwary said: "I'll have to be more careful this time. I'm positive and looking forward to come back fit again." In Tiwary's absence, Wriddhiman Saha is set to lead Bengal in the coming season. In December last year, he was prescribed six weeks rest after sustaining a back injury during the Ranji Trophy. As a result, he missed the T20I and ODI series against both England and Pakistan. Also present in the occasion, Olympian and former India football captain P K Banerjee urged the youngsters to imbibe a never-say-die attitude.
"Cricket has become very competitive these days. Playing for India is difficult but to cement your place is tougher." Praising Team India for their new-found agility, the iconic footballer said: "The Indian fielding has improved vastly. You must work hard to remain fit and agile."
