Pompey were among those adding to their ranks, with head coach Danny Cowley bringing in young Manchester City keeper Gavin Bazunu on a season-long loan on Thursday.
That’s after he landed former Luton and Millwall midfielder Ryan Tunnicliffe on a free transfer last weekend.
Both deals take the Blues up to five new arrivals so far this summer.
More are expected to follow suit.
But until then, here’s a round-up of the business concluded over the past week in the third tier – including Craig MacGillivray’s move to Charlton on a free transfer.

3. Macauley Bonne - QPR to Ipswich
The QPR striker, who was born in Ipswich, has signed for his hometown club on a season-long loan.
Bonne, 25, only joined the Championship R's from Charlton in October but started just eight league games last season.

4. Craig MacGillivray - Pompey to Charlton
The keeper wasn't offered a new deal by Pompey and that allowed League One rivals Charlton to step in to provide the 28-year-old a new home.
Moving on a free transfer, MacGillivray made 135 appearances for the Blues after arriving on a free transfer from Shrewsbury in 2018.
