Australian leg-spinner Fawad Ahmed tested positive for COVID-19 while playing in the Pakistan Super League and has been put in isolation, his club, Islamabad United said on Monday.
The Pakistan Cricket Board said all remaining members of Islamabad United have tested negative.
"One of our players, Fawad Ahmed tested positive and was immediately put in isolation two days ago," Islamabad said in a statement.
In his only appearance in PSL this year, Ahmed took 1-40 against Peshawar Zalmi on Saturday. Islamabad lost by six wickets.
Two-time champion Islamabad was due to meet Quetta Gladiators at 7 pm on Monday, but the PCB postponed the game to March 2, 2021.
It's the first COVID-19 positive test in Pakistan's premier Twenty20 league, which began on February 20.
On February 21, Peshawar Zalmi captain Wahab Riaz and head coach Daren Sammy were allowed to rejoin their squad after their appeal against a quarantine for breaching COVID-19 protocols was accepted by the PCB.
Riaz and Sammy breached the team's bio-secure bubble on February 19 when they met with their team owner, who was not part of the bubble. But they rejoined the team following two negative COVID-19 tests after which they were spared the three-day quarantine when their appeal was accepted by the PSL committee.
