Dave Jones said today that the Owls will not be signing trialists Gill Swertz, Gorka Larrea and Marek Jarolim.
The Wednesday manager still intends to inform trialist striker Marlon Harewood of a decision on him over the weekend.
Experienced midfield player Jason Koumas is to train with the club as expected, starting tomorrow or Monday.
He was due to join in earlier in pre-season but the delay has been down to a foot injury, said Jones.
Gary Madine, who has been out with severe bruising of a foot, is a doubt for Monday’s Capital One Cup tie at Oldham.
Jones dismissed as untrue a report that the Owls had made a verbal £300,000 offer for Hearts defender Ryan McGowan.
