Former Sri Lanka [Images] captain Marvan Atapattu has been named in a 15-man squad for the one-day triangular series also involving South Africa and India.

Atapattu, 35, returns after a five-month absence having recovered from an acute disc problem in his lower back that required surgery in May.

Atapattu has been a cornerstone of the top order for a decade, scoring 5,330 runs in 88 tests and 8,233 runs in 253 one-day internationals.

The selectors have decided to retain Mahela Jayawardene [Images] as captain until Atapattu has proved his fitness under match conditions.

Kumar Sangakkara will stay as vice-captain.

Atapattu has been earmarked for a new middle order role at number five following the successes of Sanath Jayasuriya [Images], Upul Tharanga and Jayawardene as the top three in England [Images].

The tri-series will be played from August 14-29 with all the matches taking place in Colombo.

Sri Lanka squad:

Mahela Jayawardene (Capt), Marvan Atapattu, Kumar Sangakkara, Muttiah Muralitharan, Sanath Jayasuriya, Upul Tharanga, Tillakaratne Dilshan, Chamara Kapugedera, Farveez Maharoof, Chaminda Vaas [Images], Lasith Malinga [Images], Dilhara Fernando, Malinga Bandara, Ruchira Perera, Prasanna Jayawardene
