Arsenal striker Chuba Akpom has moved to Hull City on a season loan, while Dame N'Doye is set for a move to Turkey.
Barnsley have signed goalkeeper Nick Townsend from Birmingham on a short-term youth loan.
Stephen McGinn has signed a new one-year deal at Watford.
The Hornets have the option of a further 12 months should the midfielder impress.
McGinn is only recently back from a cruciate knee ligament injury which kept him on the sidelines for 16 months and has yet to play a competitive game.
