Boston Town will travel to face Grimsby Borough this Saturday as their warm-up matches continue.
The Northern Counties East League Division One side are managed by former Poachers boss Dan Barrett, who played under Collins during his first stint at Tattershall Road.
Kick off will be at 3pm.
Sam O’Malley bagged a brace as Boston Town earned a 3-1 victory over Humber Premier League side Walkington at the DWB Stadium on Saturday.
Danny Trott also found the net as the Poachers stormed into a comfortable 3-0 lead at the interval.
The two strikers are already showing their goalscoring instincts, as well as their no-nonsense burly approaches to the game, ahead of the UCL Premier campaign.
Town will also travel to Spalding United (July 27) and host Wyberton (July 30) as part of their pre-season schedule.
