Rain washed out the entire morning session of the fourth day's play in the second Test between England and Sri Lanka at Lord's on Monday.
The umpires decided lunch would be taken 30 minutes early at 12.30pm local time (1130GMT) in the hope of making a prompt start to the second session.
Sri Lanka were 372 for three in reply to England's first innings 486, a deficit of 114, after rain had also forced an early close on the third day.
Mahela Jayawardene was 40 not out and Thilan Samaraweera one not out.
England lead the three-match series 1-0 after an innings and 14-run win in the first Test in Cardiff.
