Doncaster have made forward Dany N'Guessan their sixth summer signing.
Tottenham have confirmed that Romanian defender Vlad Chiriches has completed a move to Napoli.
Nottingham Forest have completed the permanent signing of Danny Fox from Southampton.
The left-back spent the last four months of the Championship season on loan at the City Ground, starting 15 games.
Fox agreed a three-year contract at the time of his initial loan deal, and that has now been activated.
The Scotland international will work under new manager Stuart Pearce next season.
