Celtic fans have started a petition for the club to reconsider their decision to partner up with online casino company Mr Green.
The Hoops launched an "exclusive slot game" offering supporters the chance to win ten pairs of tickets to the Kilmarnock clash if they sign up with Mr Green.
But the announcement resulted in severe criticism on social media with fans taking exception to the fact Celtic were promoting gambling in conjunction with giving away free tickets.
The Parkhead club's kit sponsor is bookmaker Dafabet but many supporters felt that actively encouraging betting in this manner is a step too far.
And the backlash led to one fan setting up a petition in an attempt to urge the club to "review their approach to gambling sponsorship".
