Sri Lanka captain Angelo Mathews has said that off-spinner Sachithra Senanayake's reduced potency following remedial work on his action was among the reasons he had not been picked so far in the series.
Sri Lanka's bowling has ailed against Pakistan, prompting calls for personnel changes, but Mathews felt they were already using their best bowlers.
With the spin stocks appearing bare, there have also been calls to recall Rangana Herath to the side. However, Mathews said Herath's omission was largely self-imposed.
He added that Herath said he wants to play Tests for a while, and that one dayers are a bit tough on his body, given his injuries.
