No play was possible in the Friends Life t20 game between Durham and Yorkshire at Chester-le-Street.
Rain began to fall as soon as the players took the field just before 5.30pm and although it stopped around 90 minutes later the umpires decided at 7.45pm that the efforts of the groundstaff to mop up were in vain.
Durham, who had sold 6,000 tickets in advance, remained on track for the quarter-finals, but Yorkshire's hopes were as good as extinguished by the washout.
