Sheffield Wednesday take on Stoke City tomorrow in the Capital One Cup quarter-final.
Carvalhal has operated with a rotational policy in the Capital One Cup so far, but there was a feeling that he may name a strong line-up against Stoke, as his team have progressed so far in the tournament.
A place in the semi-finals is up for grabs if Wednesday can beat Stoke, but Carvalhal is set to trust his fringe players.
As a result, the Portuguese boss intends to leave Michael Turner, Barry Bannan, Marco Matias, Vincent Sasso, Fernando Forestieri and Keiren Westwood out of his Wednesday squad to face Hull.

The six players are set to miss out on the fixture for differing reasons, with some being out injured – and others simply needing a rest.
Although Wednesday may not be playing their strongest available team, they have proven their ability to upset Premier League clubs in the competition already.
The Owls have knocked out the likes of Newcastle United and Arsenal on their route to the quarter finals, and they will be keen to cause another upset against Stoke.
Wednesday have lost just one of their last 14 matches, meaning that they have a lot of momentum on their side, going into the match at the Britannia Stadium.
