Dimuth Karunaratne is set to become only the seventh Sri Lanka player to feature in 100 Tests. His landmark game will be his last in international cricket, bringing down curtains on a near-14-year career for Sri Lanka.

Former Sri Lanka test skipper Dimuth Karunaratne will retire from the format after his 100th match, the final test of Sri Lanka's two-test series against Australia in Galle on Thursday.

Sri Lanka faces a must-win situation in the second test against Australia to level the series after a crushing defeat in the first match. The match marks Dimuth Karunaratne's final test, adding emotional significance.
