The Owls have swelled the Under-21 ranks with the signing of Sam Reed from Brighouse Town.
The 20-year-old, a left-sided defender, enjoyed a successful trial period with Wednesday last season and now signs his maiden professional contract.
Academy manager Steven Haslam said: “Sam is a hungry young player, he has good experience under the belt in senior football and joins our Under-21s.
“Sam did really well on trial with us, he impressed the coaching staff with his ability and approach to the game.
“We’re really pleased to have him on board and I would like to welcome him to the club and wish him all the very best.”
