The Cricket Association of Bengal (CAB) has told all players and officials inside the bio-bubble for the Bengal T20 Challenge to not associate with any fantasy league platforms.
A circular issued to the office bearers, players, participating clubs and match officials - revealed by Sportstar - quotes CAB chief Avishek Dalmiya: "No person involved in the bio-bubble, or any club official of the participating team would be permitted to involve themselves in any fantasy league matches pertaining to the Bengal T20 Challenge.
"Similarly, the office bearers of the Cricket Association of Bengal as well as the tournament committee members and tours and fixtures and technical committee members would not be permitted to participate in any fantasy league matches involving Bengal T20 Challenge.
"The above directions are being issued in the best interest of the association and the sanctity of the tournament and therefore, it is mandatory for the above persons to follow it diligently", the circular continued.
The six-team tournament got underway at Eden Gardens last Tuesday. Despite the CAB's apparent reservations, the competition is sponsored by fantasy sports operator Dream 11, who were also title sponsors of the 2020 IPL.
The company had previously faced a police probe for their involvement in a "fake" Sri Lankan T20 League earlier this year.
