Pallekele - Pakistan and Sri Lanka will ring in several changes, most of them forced on them, in a bid to win the decisive third and final Test starting in Pallekele on Friday.
Both sides are pulling out all the stops to break the 1-1 deadlock after Pakistan won the first Test by 10 wickets and Sri Lanka responded with a seven-wicket victory in the second.
For the first time in 15 years since Kumar Sangakkara's debut in July 2000, Sri Lanka will go into a Test without either him or the retired Mahela Jayawardene in the ranks.
Sangakkara, Test cricket's leading current run-getter, committed himself to playing just two Tests against Pakistan and two more against India in August before retiring.
Sangakkara, who has 12,305 runs from 132 Tests, will be replaced at his pivotal number three position by another left-hander Upul Tharanga, 30, who played the last of his 19 Tests a year ago.
"It's a strange experience to be without Mahela and Sanga, but we have some good young players who are ready to step in," vice-captain Lahiru Thirimanne told reporters on Thursday.
"Upul has been around for a long time and understands the demands of Test cricket."
Fast bowler Dushmantha Chameera, who suffered a side strain on his debut in the second Test in Colombo, will undergo a fitness test before he is picked for the crucial match.
"Chameera is 50-50 for the Test," said Thirimanne. "It is not yet certain if he will play."
Sri Lanka are planning a three-man pace attack, instead of two as in the previous Tests, on a greenish Pallekele stadium pitch that should favour seam movement on the opening day.
"It's a good wicket for batting, but it does help the fast bowlers at the start," said Thirimanne. "We may play three seamers and just one spinner."
Veteran left-arm spinner Rangana Herath, who managed to take just two wickets in the first two Tests, is likely to be dropped, leaving young off-break bowler Tharindu Kaushal as the chief spin option.
If Chameera is unfit, seamer Suranga Lakmal will make his first appearance in the series to share the new ball with Dhammika Prasad and Nuwan Pradeep.
Pakistan are forced to make two changes, with pace spearhead Wahab Riaz ruled out because of injury and all-rounder Mohammad Hafeez not available since he has to undergo mandatory tests after being reported for a suspect action in the first Test.
"At least we have 11 players to pick from," skipper Misbah-ul Haq said on Thursday. "We have a lot of options and each one of them is focused on doing well for the country."
Left-hand batsman Shan Masood is likely to replace Hafeez at the top of the order and left-arm seamer Rahat Ali could come in for Wahab, but Misbah indicated the team had not been finalised.
"We will field a combination that is good enough to win the match," he said. "With Jayawardene and Sangakkara not there, this is our best chance to beat Sri Lanka."
