Sri Lanka omitted vice captain Dinesh Chandimal from a 15-member squad and brought in three uncapped players for a two-Test tour of Zimbabwe next week.
Sri Lanka Cricket said Chandimal was yet to recover from a thumb injury he sustained during a domestic match last month.
The three new faces in the squad are fast bowlers Kasun Madushanka and Lahiru Kumara and the allrounder Asela Gunaratne.
The first Test begins on October 29 in Harare while the second is scheduled from November 6 at the same venue.
The Test squad: Angelo Mathews (capt), Dimuth Karunaratne, Kaushal Silva, Kusal Perera, Kusal Mendis, Dhananjaya Silva, Rangana Herath, Dilruwan Perera, Lakshan Sandakan, Suranga Lakmal, Niroshan Dikwella, Kasun Madushanka, Lahiru Kumara, Lahiru Gamage and Asela Gunaratne.
