BFC, runners-up in 2016, were earlier scheduled to play on April 28.
They will now travel to Maldvies to take on hosts Club Eagles next month for the group D fixture.
“The sub-committee also agreed to award the Playoff Stage slot to Club Eagles, who will now face India’s JSW Bengaluru FC for a place in the AFC Cup Group D on May 11, 2021 in Maldives,” Asian Football Confederation (AFC) said in a press release on Friday.
BFC were earlier drawn to play the winners of the match between six-time Bangladesh Premier League champions Abahani and Maldives’ Eagles.
However, a countrywide lockdown and travel restrictions in Bangladesh forced Abahani to withdraw from the tournament.
