Game at Boots & Laces starts at 12pm against the Hatters.
Southend United U21s are back in action tomorrow at Boots & Laces Training Ground for a Final Third Cup game against Luton Town.
The clash kicks off at 12pm, with boss Dave Robertson aiming to continue his winning run at the helm of the U21s.
There is a chance that Adam Thompson could play a part in the game against the Hatters.
Dave said: “With it being a 12pm kick off, we're hopeful there could be a number of supporters who could come down and support the lads.
“With the first team playing at Crawley in the evening, those that are aiming to watch them, can come along and watch the U21s earlier in the day.”
