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.
QPR midfielder Akos Buzsaky has left Loftus Road after failing to agree terms on a new contract.
Buzsaky was offered a new deal at the end of last season but believes his future lies elsewhere, ending his four-year spell in west London.
"The club is thankful to Akos for his contribution and wishes him every success for the future," read a statement on the club's official website.
Buzsaky played only a role in QPR's escape from relegation last season, scoring two goals in 21 appearances.
