Sri Lanka captain Sanath Jayasuriya will have to put up with pain from his broken thumb for the rest of the World Cup, according to team physiotherapist Alex Kountouri.

"Sanath's forearm is not a problem but the left thumb is broken right at the tip and he will only fully recover after the World Cup," he said.

"He is taking mild pain killers but can manage the pain for the time being."

Jayasuriya, however, may have to hide himself in a backwater while fielding.

Kountouri said: "The only problem for Sanath would be if he was struck hard on it while fielding."

Batsman Hashan Tillakaratne, meanwhile, is recovering from a hamstring strain after missing the Super Six defeat against India.

"It is not serious and he will be fit for Saturday's game (against Zimbabwe)," Kountouri said.

Sri Lanka are fifth in the Super Six table and must win their final game against Zimbabwe to have any chance of reaching the semi-finals.
