Former Sri Lanka captain Angelo Mathews has recovered from injury and was named Wednesday in a 22-player squad to face England in two Tests in Galle.
But the injured pair of batsman Dhananjaya de Silva and pace bowler Kasun Rajitha will miss the series starting Thursday after being part of the 2-0 Test series defeat in South Africa this month.
Mathews, 33, did not make the South Africa trip because of a hamstring injury but is expected to line up against England in matches that count towards the inaugural world Test championship.
The Dimuth Karunaratne-led team will resume a series that was halted in March after England flew home because of coronavirus fears.
Both matches will be played in Galle behind closed doors.
Sri Lanka squad: Dimuth Karunaratne (capt), Kusal Janith Perera, Dinesh Chandimal, Kusal Mendis, Angelo Mathews, Oshada Fernando, Niroshan Dickwella, Minod Bhanuka, Lahiru Thirimanne, Lasith Embuldeniya, Wanindu Hasaranga, Dilruwan Perera, Suranga Lakmal, Lahiru Kumara, Vishwa Fernando, Dushmantha Chameera, Dasun Shanaka, Asitha Fernando, Roshen Silva, Lakshan Sandakan, Nuwan Pradeep, Ramesh Mendis

Bairstow, 31, believes he has a lot to learn from the South African legend Kallis who is in isolation in Sri Lanka and should join the squad on Friday.
Bairstow, 31, scored a century in his last one-day international and then amassed 345 runs in the IPL Twenty20 tournament for Sunrisers Hyderabad between September-November.
On arrival, the contingent will spend 10 days in a bio-secure bubble in Hambantota, according to a report in Sky Sports.
