Zian Flemming arrived on a late deal from Millwall to make it three new signings on the final day. Jeremy Sarmiento and Josh Laurent also arrived from Brighton and Stoke City respectively.
Going the other way on deadline day, meanwhile, was Luke McNally, who reunited with Scott Twine at Bristol City, and Vitinho, who completed his return to Brazil to sign for Botafogo for an undisclosed fee.
