Graham Drury resigned as co-boss of Holbeach United on Saturday night.
The former Stamford, Corby Town and Boston United manager quit after guiding the Tigers to a 4-3 United Counties League KO Cup win over Olney Town.
The exact reasons for his departure are yet to be determined, but Drury himself confirmed his exit to The Spalding and South Holland Voice on Sunday.
He leaves John Chand in sole charge at Carter’s Park, with Holbeach still very much in the hunt for a UCL double.
Drury only joined the club in the summer, as he and Chand replaced outgoing chief Glen Maddison.
The Tigers have yet to officially comment on the exit, but have promised to provide official details tomorrow.
We also expect updates from Drury and Chand on Monday.
More on this story when we have it.
