The first Test between Pakistan and England in Rawalpindi will start as scheduled today after the visitors passed a medical assessment on the morning of the match. However, changes are expected to the playing XI that England had announced 48 hours ahead of the match.

Following an assessment by Dr Peirce and Dr Biswas of the touring group, many of whom were confined to their hotel rooms on Wednesday, the results confirmed England would be able to field an XI.

A joint statement from the ECB and PCB said: "The ECB has informed the PCB that they are in a position to field an XI, and, as such, the first Test will commence as per schedule today (Thursday, 1 December) at the Rawalpindi Cricket Stadium."

The make-up of the team, however, is subject to change. Captain Ben Stokes, who named his side on Tuesday, James Anderson and Jack Leach were among the worst affected, with others due to play also battling to shake off the bug. Training on Wednesday was optional with only Harry Brook, Zak Crawley, Keaton Jennings, Ollie Pope and Joe Root attending the session. All bar Jennings had been named in the initial team, along with a debut for Liam Livingstone, a recall after six years for opener Ben Duckett, Ben Foakes, and Ollie Robinson.

England will leave the Serena Hotel at 8am as originally planned and will name their XI at the toss, which is due to take place at 9.30am local time.
