Dilshan is doubtful for the fifth ODI after hurting his thumb.
Abu Dhabi: Restoring pride will be the only thing on Sri Lanka's mind when they take on Pakistan in the fifth and the final one-day international here on Wednesday.
Pakistan have an unassailable 3-1 lead in the five-match series after winning the first match by eight wickets before Sri Lanka levelled the series with a 25-run victory in the second. Pakistan then came back to win the third match by 21 runs. Shahid Afridi's all-round performance helped Pakistan clinch the series in the 26-run win in the fourth match.
Sri Lanka will also be without the services of experienced batsman Mahela Jayawardene, who has been ruled out of the last ODI and the only T20 to be played on Friday.
The 34-year-old batsman hit a half-century in the last game in Sharjah on Sunday, but played in some discomfort after injuring his knee.
Jayawardene returned home to regain fitness ahead of team's tour of South Africa next month. Chamara Silva has been brought in as Jayawardene's cover.
The 31-year-old Silva has played 11 Tests and 74 one-day internationals for Sri Lanka.
Tillakaratne Dilshan was okay after hurting his left thumb and if it does not get worse, he will be available to play in the Twenty20 match between the two teams on Friday.
Pakistan are brimming with confidence and will look to make it 4-1 on Wednesday.
