Sri Lanka did not name individual squads for the ODI and T20I matches, opting instead to name a combined squad of 24 players for the tour.
Olly Stone was due to be named in England's ODI squad, but was ruled out of the rest of the season with a stress fracture to his back. As a result,
George Garton earned his maiden call-up to the England team. England's
Jos Buttler suffered a calf tear in the first T20I and was ruled out of the rest of the series.
Dawid Malan was added to England's ODI squad as Buttler's replacement. Sri Lanka's
Avishka Fernando was ruled out of the ODI series, after suffering a quadriceps tear in the second T20I match. England's
Dawid Malan was also ruled out of the ODI series, for personal reasons.
Tom Banton was added to England's squad for the third ODI, as cover for Malan. On 28 June 2021,
Sri Lanka Cricket suspended
Kusal Mendis,
Danushka Gunathilaka and
Niroshan Dickwella after they breached the team's
bio-secure bubble. All three players were seen in the city centre of
Durham, with them all being sent back home ahead of the ODI matches. In July 2021, Sri Lanka Cricket suspended all three of them from playing in international cricket for one year. Sri Lanka Cricket agreed to lift the ban on all three players early, rescinding the punishment in January 2022. ==Tour matches==
