The Whites’ talented under-21s players, under Redfearn’s expert guidance, will be on show in Saturday’s pre-season friendly.
Redfearn played for the Pilgrims between 2002 and 2004 during his spell as assistant manager and was a popular figure throughout his time at York Street.
For Boston boss Dennis Greene, it will be another opportunity to put his players through their paces following midweek friendlies against Lincoln United and Spalding United.
Goalkeeper Ashley Timms could feature — while striker Marc Newsham will be back in contention after his stint in Russia with the Great Britain squad.
