Brentford have been drawn to face Sky Bet League Two side Grimsby Town away from home in the fourth round of the Carabao Cup.
The Bees will travel to Blundell Park on Tuesday 28 October (7.45pm kick-off GMT).
Keith Andrews' side have defeated fellow Premier League clubs Bournemouth and Aston Villa to reach this stage of the competition.
