Sri Lanka Cricket will refuse no-objection certificates to at least 16 centrally-contracted players seeking to take part in this year's Bangladesh Premier League.
The board will instead insist that its cricketers take part in the upcoming Premier Limited Overs tournament at home.
Some of the players who have been bought by BPL franchises may also be required for Sri Lanka's Test tour of New Zealand, which begins in early December.
The BPL runs from November 22nd to December 15th.
The move is aimed to protect the quality of the Premier Limited Overs tournament, and to help ensure Sri Lanka's clubs have their best players available to them throughout the season.
