Gay is expected to be fully fit for the Test series after he retired hurt with a shoulder injury while batting for Durham in the One-Day Cup last week. Fisher is short on cricket after bowling only ten balls in the Hundred, but is one of seven seamers in England's Test squad. Sussex's Tom Haines will captain the side, which also features recent England Under-19s players Luc Benkenstein, Caleb Falconer and Manny Lumsden. The squad does not contain any players required for their counties or franchises in the knockout stages of the One-Day Cup or the Hundred. Pakistan arrived in the UK from their drawn Test series in the Caribbean against West Indies on Saturday, and have been training at Beckenham this week.
