Sri Lanka ODI Skipper Angelo Mathews participation in the tri-nation ODI series in Bangladesh remains uncertain, SLC sources said. 

They added that Mathews is currently under medical observation for not a hamstring tightness. 

The SLC said a statement on the condition of the Sri Lankan skipper would be made tomorrow. 

Dinesh Chandimal will lead the Sri Lankan ODI team during the tri-nation series, in the permanent captain's absence.
