Afghanistan spinner Mujeeb Ur Rahman has been released from a Gold Coast hospital and has joined the Brisbane Heat in Canberra after recovering from Covid-19.

Mujeeb is set to be available for Monday night's clash with the Sydney Thunder but it remains to be seen whether he will be selected after he was hospitalised following a positive test for Covid-19 while in quarantine in Australia.

The Heat confirmed on Saturday that Mujeeb had been released from hospital and had been able to board a flight to Canberra.

Heat captain Chris Lynn spoke after the Heat's loss to the Melbourne Stars on Friday night and was optimistic Mujeeb could play on Monday despite his limited preparation.

"He's really upbeat," Lynn said. "He can't wait to play. He has been part of our Heat family for a number of years now. He's a world-class player and can be a game-changer."

Mujeeb's countrymen Mohammad Nabi, Noor Ahmad, and Zahir Khan are still in quarantine after being delayed trying to get to Australia for the BBL.

The trio where initially supposed to land in Adelaide in November but a Covid outbreak in that city forced their flight to be cancelled and they could not board another flight until nine days later due to the Australian government's restrictions on the number of daily overseas arrivals.

Khan should be available for the Melbourne Stars third match against the Perth Scorchers in Launceston on Wednesday while Nabi and Ahmad should be available for the Melbourne Renegades third match against the Hobart Hurricanes in Hobart next Saturday.
