Duckett was fielding at slip when Abrar Ahmed, Pakistan’s No. 11, steered a short ball from Joe Root straight into the tip of his thumb. He held onto the catch at the second attempt but immediately winced in pain, and received treatment from England’s doctor Glen Rae as he walked off the field.

An England spokesperson said that the team are hoping Duckett’s injury will settle down overnight and that he is not due to go for a scan, but it was not clear on Tuesday evening whether he will be available to bat on the third day.

It would be a significant blow for England to lose Duckett, not least after opting to continue with their six-batter, five-bowler formation in the absence of Ben Stokes. He was England’s second-highest run-scorer in their 3-0 series whitewash in Pakistan two years ago and, with an average of 44.05 in 23 Tests since his recall for that tour, has emerged as one of their most important players.

Stokes is targeting the second Test for his comeback from a torn hamstring and stepped up his recovery on Tuesday. He took slip catches and did some high-intensity running before play started, batted in the nets behind the Waqar Younis Stand for around 45 minutes at lunch, and bowled three overs at tea with James Anderson – back with the squad after competing in a pro-am golf tournament last week – watching on.
