Bengaluru: Chennai Super Kings (CSK) have submitted a formal grievance to the Board of Control for Cricket in India (BCCI) regarding the conduct of Royal Challengers Bengaluru (RCB) during their IPL 2026 fixture on April 5.

The complaint, which targets actions at the M. Chinnaswamy Stadium, specifies issues including discriminatory in-stadium entertainment and the alleged mistreatment of Chennai supporters. The move introduces a new degree of friction to a rivalry already strained by RCB’s recent streak of four consecutive victories over the Chennai franchise.

Allegations of Identity Stereotyping

A central pillar of the complaint involves a song broadcast during the game. According to a report by the Indian Express, which cited sources within the franchise, the track contained repetitive references to "dosa, idli, sambar, chutney." The Chennai management contends these lyrics were utilised to stereotype and lampoon the regional identity of Tamil Nadu.

CSK managing director Kasi Viswanathan addressed the shift in stadium atmosphere during the Bengaluru match. "The DJs are usually around to support the home team. But at the Chinnaswamy Stadium, it was different," Viswanathan told the Indian Express. "Certain comments were made against our players. Considering it, we have written to the BCCI to have a look into it."

A History of Musical Provocation

The track in question, produced by artist Gana Appu, has a contentious history between the two clubs. The friction began last season when RCB published a video of wicketkeeper Jitesh Sharma singing the lyrics before a game in Chennai, sparking a social media backlash.

In a retaliatory move during the return leg at the Chepauk stadium, the Chennai DJ played the same song upon Sharma's dismissal. However, the CSK administration reported that it took internal measures to prevent further incidents.

"Since then, there has been no repeat. The DJ is not supposed to make comments on opposition players, and we are fortunate to have a fanbase that supports us in great numbers," Viswanathan remarked.

Professional Conduct in Question

Chennai management asserts that while they addressed their internal protocols, the April 5 match in Bengaluru saw the opposition cross established professional boundaries. The franchise specifically objected to the DJ’s commentary following the dismissals of Chennai players.

The Super Kings argued that while a stadium DJ's primary function is to invigorate the home crowd, the role should not extend to the ridicule or targeting of the visiting team. The BCCI is expected to review the correspondence as the league manages the fallout from one of its most high-profile inter-city disputes.
