Balaji and Venkatesh Rao, two key figures in the Venky’s group, were harassed by fans before the relegation crunch at Wigan.
Their entourage, including the club’s legal advisers, sat through a difficult first half when their side struggled and the away support turned on Kean – and the owners.
The Rao delegation chose to call up their chauffeur-driven cars and quit after the break.
The Venky’s pair had flown into England on a PR exercise – after stating they would not sell the club – and they were also due to discuss player budgets with Kean and transfer ‘fixer’ Simon Hunt.
However Rovers are stuck in the bottom two, four points from safety, and the Indians did not enjoy their day.
Kean has been backed by family ‘ruler’ Mrs Arundhara Desai, but the crisis is a big test for the manager.
