Blackburn Rovers have completed deals for Poland international goalkeeper Grzegorz Sandomierski and Portuguese duo Diogo Rosado and Nuno Henrique.
Sandomierski, 22, has three caps and joins on a season-long loan from Genk.
Attacking midfielder Diogo Rosado, also 22, has signed from Sporting Lisbon, while defender Nuno Henrique, 25, joins from Academica De Coimbra.
They have agreed three-year deals at Ewood Park, but all three will not be able to face Leeds on Saturday.
Rovers broke their transfer record on Thursday to sign striker Jordan Rhodes from Huddersfield Town, for a fee which could rise as high as £8m.
