Offspinner Sachithra Senanayake will replace the injured Ajantha Mendis in Sri Lanka's squad for the remainder of the ODI series in South Africa. Mendis had a recurrence of his back problem ahead of the second match in East London.

"Ajantha Mendis will return to Sri Lanka from South Africa due to injury and will not be available for the remainder of the series. Sachitra Senanayaka will leave for South Africa immediately," Sri Lanka Cricket said.

Senanayake, 26, has been playing on Sri Lanka's domestic circuit for more than five years. He has represented Ruhuna and Sinhalese Sports Club, and picked up 297 wickets in 59 games at an average of 20.50 in the first-class format. In List A cricket, he has 107 wickets in 66 matches at 18.73.

In Tier A of the Premier League Tournament, Sri Lanka's first-class competition, Senanayake was the fourth-highest wicket-taker last year, with 45 in eight matches at 15.17. He topped the wicket charts in the Premier Limited Over Tournament, the domestic List A competition, taking 16 wickets in six matches at 11.18.

Senanayake is likely to be available for the third ODI on January 17.
