Burnley have announced they will play Celtic in a friendly.
The English Championship club have confirmed their plans for pre-season with a warm-up match against the Scottish champions listed among four other behind-closed-door friendlies.
A match against Burnley has not been publicly announced by Celtic in their pre-season preparations.
Brendan Rodgers' side have already played Ayr United and Queen's Park this summer and have matches against DC United, Manchester City and Chelsea lined up in America.
However, Burnley's announcement appears to have rumbled a 'secret' friendly with Celtic at their training ground.
The Celtic B team will also play against Burnley's academy side in a pre-season match on Saturday, July 13.
