"I haven't had a chance to talk to Mitchell or anyone else involved. It's obviously something we don't want to see on the cricket field. But we will wait for match referee (Andy Pycroft) to make his ruling," Vettori said after the match here last night.
"I am sure the match referee would be involved. Let's wait and see what he says before we speculate. I think we should sit tight and not judge the incident," he added.
The incident referred to was the hurling of the cricket bat by West Indies all-rounder Pollard at Australian left-arm pacer Starc after the latter delivered the ball to him despite the batsman having backed off from the crease.
It was an ugly incident as Pollard had advanced menacingly at Starc before throwing his bat which, luckily, hit the turf well away from the bowler.
Both players had to be separated by umpires S Ravi and K Srinath and they had a talk with RCB captain Virat Kohli too while RCB's West Indian player Chris Gayle pacified Pollard.
Strangely IPL organisers gagged the media from asking MI wicket-keeper batsman C M Gautam about the incident with the media manager issuing a diktat before the start of his interaction.
Vettori blamed the fall of crucial wickets when asked about RCB's failure to chase the stiff target of 187 set by MI and falling short by 19 runs despite a rollicking start given by Chris Gayle and Parthiv Patel.
"It was a tough total to chase in a T20 Game is hard. The start we got was fantastic, Chris and Parthiv set the tone with 44 in 21 balls and Virat picked it up as well. Thereafter we lost crucial wickets which put us under pressure," he said.
