According to Pakistan Cricket Board (PCB): "Naseem’s return, however, is dependent on the fulfilment of bio-bubble protocols, which include testing negative within 48 hours prior to the integration in the bubble and subsequent isolation along with two repeat COVID-19 tests before boarding the next chartered flight which will leave from Pakistan."
