Pradeep will join the team today after returning from Zimbabwe, where he was travelling with Sri Lankan A team for a tri-series.
Pradeep has played three Tests but is yet to play in a One-day international.
Pradeep had made his Test debut against Pakistan in Abu Dhabi in October 2011.
Kulasekara had strained his groin while attempting a catch in the first one-dayer against India on Saturday. He bowled only half of his quota of overs.
The two teams are set clash in the second one-dayer, here tomorrow.
