Sometime during the second day's play of the ongoing test (Ind Vs Zim) at Bulawayo, umpire Daryl Harper left the field and the third umpire Russel Tiffin stepped into officiate. It is not often that a substitute umpire comes onto the field. Say Ricky Ponting is at the crease and is given out LBW by the substitute umpire. Would he throw a tantrum? OK, I know, :) am being out of line. I just love to kid the Aussie captain.
