According to media reports, uncertainty over the venue has arisen after the Karnataka State Cricket Association (KSCA) failed to secure police approvals by the August 10 deadline. As of Tuesday, the local police had yet to complete the necessary procedures to grant the required permissions. The Board of Control for Cricket in India (BCCI) had earlier instructed the KSCA to obtain all approvals by last Saturday. Chinnaswamy Stadium Deemed Unsafe It may be recalled that the KSCA had to shift the ongoing Maharajah T20 Trophy to Mysuru even after deciding to conduct it behind closed doors at the Chinnaswamy Stadium. The KSCA had to shift the tournament after the one-man D'Cunha Commission declared the Chinnaswamy Stadium unsafe for large events. The state government set up this commission to investigate the 4 June stampede in which several people died and many others were injured during Royal Challengers Bengaluru's IPL victory celebrations. If Not Bengaluru, Then Where? Meanwhile, the Greenfields Stadium in Karyavattom, Thiruvananthapuram, has emerged as a possible alternative venue to host the matches scheduled in Bengaluru. The ICC showpiece's tournament opener between India and Sri Lanka is currently scheduled to be played at the Chinnaswamy Stadium on September 30, followed by matches between England and South Africa (October 3), India and Bangladesh (October 26), the second semifinal on October 30, and the final on November 2. It has been reliably learnt that Kerala Cricket Association officials have been asked about the competition schedule and the venue's readiness to host the big-ticket matches in just over a month's time. As per ICC guidelines, the host association needs to hand over the venue to the global governing body 30 days prior to the tournament's beginning, and no other matches should be held at the stadium in that period. However, the Greenfields Stadium is scheduled to host the Kerala Cricket League (KCL) matches between August 21 and September 7, but the KCA officials are confident of moving the T20 matches to another venue if the World Cup games come their way. "We have backup venues, if the World Cup matches are shifted here. But as of now we are waiting for a final confirmation," sources close to the development told PTI. The KSCA officials did not respond to questions regarding the possible venue change, but it is learnt that they have put forward the proposal of holding the World Cup matches behind closed doors in order to secure the police approval.
