Former India skipper Dilip Vengsarkar, while broadly agreeing to the views expressed by umpire Steve Bucknor on video referrals, is apprehensive that on-field umpires will tend to play safe and refer a majority of appeals to the third umpire, leading to more stoppages.

"I tend to agree with him. But the problem will arise if the on-field umpires, as they are prone to do currently in case of run out appeals, prefer to refer them to the third umpire even though they are not marginal decisions. This could lead to more stoppages and delays," Vengsarkar told PTI today.
