Chamara Silva, a middle-order batsman, has joined Sri Lanka's squad in the UAE as back up for Tillakaratne Dilshan and Mahela Jayawardene, who are both injured.

While the extent of Dilshan's niggle is not known, Sri Lanka Cricket (SLC) already announced that Jayawardene will not be considered for selection for the Twenty20 international against Pakistan in Abu Dhabi on November 25.

SLC also said that fast bowlers Nuwan Kulasekera, Dhammika Prasad and Shaminda Eranga, as well as wicketkeeper Prasanna Jayawardene, will not be considered for the Test series in South Africa because of injuries.

Sri Lanka lost the five-ODI series against Pakistan after a third defeat in Sharjah on November 20. The final one-dayer is in Abu Dhabi on November 23, followed by the T20 two days later. Sri Lanka's tour of South Africa begins with a tour match on December 9, followed by the first Test on December 15.
