Who Opens After Pathum Nissanka’s Hamstring Injury Rules Him Out of the ODI Tri Series 2026?

Sri Lanka needs a new top-order partner after Nissanka failed to gain medical clearance, and the replacement confirmed on 15 October is Lahiru Udara. Avishka Fernando, who has batted at the top with Nissanka before, is the experienced option. Udara has never played an ODI, but he smashed 91 off 55 balls against Pakistan in a T20I on 9 October. No recovery timeline has been attached to the injury, so a quick return looks unlikely, and the opening slot is wide open for the whole competition.

A Late Blow for Sri Lanka

Sri Lanka Cricket confirmed on 15 October 2026 that Nissanka had not obtained medical clearance, and Lahiru Udara was named to take his place in the squad. The problem is a left hamstring injury, and no timeline for recovery has been given. That silence makes it hard for the selectors to plan beyond the opening games of the competition, because nobody can say whether he will be back for the later fixtures. They must now build an opening combination without the batter who anchored it.

The trouble began during September’s white-ball tour of England, where he batted through the third ODI while uncomfortable and then struggled badly in the last one. The same hamstring had already kept him out of the Pakistan T20Is, for which the squad was named on 2 October. An unrelated wrist complaint resurfaced in June, led to surgery in the UK and cost him the LPL and the India Tests. His body has simply not cooperated all year, and Sri Lanka have paid for it in selection headaches.

The most obvious replacement at the top is Avishka Fernando, who has 51 ODIs, 1,589 runs and an average of 31.78, with a highest score of 127. Those figures were recorded as of April 2025, so they say little about his form now. He has opened alongside Nissanka before, against Afghanistan in February 2024, which gives him a template to follow. His recent returns remain the missing piece.

Mishara is another name in the mix, who piled up 1,794 runs at 40.77 from 53 List A games before his ODI debut. That average is sturdy, yet his international record and any history of opening the innings are nowhere to be found. Choosing him would be a gamble on domestic form translating to a higher level against better bowling. Sri Lanka may prefer a proven partner for Kusal Mendis at the top.

Udara Gets His Big Chance

Udara arrives with no ODI appearances, so everything about him is based on domestic and T20 numbers. His List A record stands at 3,017 runs at an average of 32.09, which is solid without being spectacular. In T20 cricket, he has 2,010 runs from 94 matches at 23.92. Those numbers describe a busy, reliable batter rather than a destructive one, and that profile could suit the early overs of a one-day innings.

His 91 off 55 balls against Pakistan on 9 October is the knock that changes the picture. It showed he can score quickly against international pace and handle pressure in a big setting. ODI cricket asks for more patience, and a batter has to survive the new ball before he can attack. If he adapts quickly, Sri Lanka will have found a fresh opener at exactly the moment they needed one, and the injury will look less damaging than it first did.

Rathnayake and the Final Call

Rathnayake offers a different kind of option. He has played four ODIs and scored 194 runs at an average of 48.50, including 121 at number four against England in January 2026. That century proves he can finish big innings against a strong attack. Whether he has ever opened in a professional match is not on record, so moving him up would be a leap.

The predicted XI lists Kusal Mendis first and Udara next, though it does not say who opens. No recent ODI opening pair is on record either, which leaves the selectors with plenty of freedom. They can choose experience, form or a surprise at the top. The ODI Tri Series 2026 Nissanka hamstring injury has turned a settled opening slot into the biggest selection puzzle in the squad.
