Hayden Walsh, a West Indies legspinner has been found Covid-19 positive after being tested twice in the last two days in Dhaka.
As a result, he has been ruled out of the ODI series against Bangladesh and the tourists haven't named a replacement yet.
Walsh, who is asymptomatic tests, tested positive on Wednesday and Thursday tests. However, upon arrival in Dhaka on January 10, he had tested negative.
Now he is in self-isolation until he gets two negative results, reports ESPNcricinfo.
According to a Cricket West Indies (CWI) statement, he had no contact with the other squad members.
"In accordance with the established medical protocols, Walsh remained isolated from the West Indies squad and is now under the care and supervision of the Team Physician, Dr Praimanand Singh," the CWI statement read. "All other members of the West Indies touring squad returned second negative Covid-19 tests, after undergoing four tests within the last 11 days."
Both the West Indies Test and ODI squads began training on Thursday after three days of room isolation at the team hotel in Dhaka. Bangladesh's 24-member preliminary ODI squad is also staying at the same hotel.
Walsh, who has played a combined 10 ODIs and 17 T20Is for West Indies and United States of America, was the senior spinner in the squad and expected to form a spin-bowling partnership with newcomer Akeal Hosein in the ODI series.
The two West Indies squads will continue training in separate groups from Friday, before the ODI squad travels to BKSP on 18 January to play their only warm-up game. The first two ODIs of the series are in Dhaka on 20 and 22 January, while the third ODI is in Chattogram on 25 January.
