A second-string India side will start their ODI series in Sri Lanka as favourites, with the hosts heading into Sunday's opener in Colombo against a backdrop of multi-faceted chaos.

The start of the series was delayed by five days due to a coronavirus outbreak in the Sri Lanka camp, with batting coach Grant Flower and team data analyst GT Niroshan testing positive for the Delta variant.

Sri Lanka's squad were allowed to leave isolation and resume their preparations last weekend after returning negative PCR tests.

ESPNcricinfo reported team doctors believed Flower and Niroshan's infections stemmed from the recent tour of England, where the home team suffered a breach of their bio-secure bubble that forced them to name a reserve line-up for their subsequent ODI games against Pakistan.

Although Sri Lanka do not find themselves in quite such a selection bind, they remain without deposed captain Kusal Perera due to a shoulder injury and Niroshan Dickwella, Kusal Mendis and Danushka Gunathilaka remain suspended for breaking COVID-19 protocols during the England tour.

Dasun Shanaka will skipper the team, a previously bit-part white ball player having ascended to the role amid a stand-off between Sri Lanka's players and their board over playing contracts.

They will emerge from a troubled period to take on an India side captained by opener Shikhar Dhawan and with pace bowler Bhuvneshwar Kumar second in command.

India batting great Rahul Dravid has been named as coach for the tour, with the first-choice side awaiting their forthcoming series in England.

Batsmen Devdutt Padikkal, Ruturaj Gaikwad and Nitish Rana, all-rounder K Gowtham and left-arm seamer Chetan Sakariya have all been handed maiden call-ups.

Shikhar Dhawan

Bhuvi ready to put injury woes to one side

Kumar will be the leader of fast bowling unit also featuring Sakariya, Navdeep Saini and Deepak Chahar. Having been beset by injury problems over recent years, he was back to his best in the March limited-overs series against England. In the ODIs, he took six wickets at a miserly economy rate of 4.65.

Shanaka must show leadership class

Irrespective of how and why Shanaka became Sri Lanka captain, he is now the man in possession of a role that tends not to promise longevity for incumbents. He will need to improve upon 611 runs and 10 wickets from his 28 ODI appearances to date to turn some unhelpful conversations around.
