Chesterfield's Jordan Burrow and midfielder Derek Niven have returned to the club following the completion of their loan spells.
Burrow spent two months with Blue Square North side Boston scoring twice in 11 appearances, seven of which were from the bench.
Both of the 19-year-old's goals proved to be matchwinners, with headers securing victory for the Pilgrims against Droylsden in September and Workington the following month.
Meanwhile, Derek Niven is also back at the B2net Stadium after his loan spell at Northampton.
The experienced midfielder made four appearances for the League Two club following his switch at the end of October.
