Sri Lanka, tipped as one of the title contenders, lost to Pakistan by 11 runs on Saturday and they would look to lift their morale with a big win against Kenya at the R Premadasa Stadium.
They have also got the boost ahead of Tuesday's match with fast bowler Lasith Malinga available for selection after sitting out of Sri Lanka's last two matches due to a sore back.
Sri Lanka can ill-afford to take their opponents lightly, though Kenya had suffered heavy defeats at the hands of New Zealand and Pakistan in their last two matches and facing internal division with differences between their coach Eldine Baptiste and senior players.
Against the Kiwis, Kenya were bowled out for 69 runs, their lowest total in ODI cricket, and then Pakistan thrashed them by 205 runs at Hambantota.
However, the last time Sri Lanka and Kenya met in a World Cup encounter was in 2003 and the Africans had stunned the 1996 champions on that occasion with an upset win in Nairobi.
Understandably, Sri Lanka coach Trevor Bayliss warned his players not to be complacent.
"The fact that we did not win our last game will stop any complacency. Our guys are consciously aware of playing good cricket and we certainly will not take them lightly," Bayliss said.
He said Malinga was able to bowl full steam at the nets on Monday and he would be available for selection.
"Lasith bent over to pick up a cricket ball about two weeks ago and strained his back a little. The physio said that the first two weeks were the most important after his injury as the most likelihood of him re-injuring was that period. He bowled in the last two practice sessions. He has bowled with a full run-up today and batted and fielded.
We have a selection meeting in the evening and will decide what to do then," Baylisss said.
Kenya, on the other hand, are facing trouble ahead of their all-important match with reports of differences between players and coach emerging.
Cricket Kenya chief Samir Inamdar on Sunday blamed differences between the players and West Indian coach Eldine Baptiste for their lacklustre performances so far.
Kenyan captain Jimmy Kamande, however, dismissed suggestions that there was disunity within the squad and promised a better performance on Tuesday.
"I also read those reports. I have not spoken to the chairman, but I can tell you that my team is very solid. When a team loses people try to find excuses. The thing is we have not performed and we want to play well," Kamande told reporters at the pre-match press conference.
"Obviously Sri Lanka are a solid side. But we have nothing to lose. They are the ones who are under pressure to perform. Having lost to Pakistan, this makes a must win game for them and we will try and put pressure on them," Kamande added.
