Lasith Malinga will leave the Sri Lankan team following their World Cup Game against Bangladesh, which will be played in Bristol on Tuesday, 11 June, following the death of his mother-in-law.
Malinga, however, is expected to be back for Sri Lanka's next game, against Australia, which will be played on 15 June.
The fast bowler is seen as crucial to his team's chances at the World Cup, bringing along a wealth of experience and past success. His spell of 3/39 against Afghanistan helped Sri Lanka defend a modest total of 201 in a rain-marred game in Cardiff.
The Dimuth Karunaratne-led side is currently placed sixth on the table, with three points in their kitty.
