Reddick joins the Devils from Denmark’s Aalborg Pirates where he scored eight goals with 25 assists in 58 games last year. He led the Danish league in assists for defensemen in 2016/17.
The 27-year-old has previously iced in Norway, France and with the ECHL’s Las Vegas Wranglers.
Devils’ boss Andrew Lord said: “Bryce is a good skater and has a knack for scoring goals. He has a great one-timer and can jump into the play to join the rush.
“He moves so well, and is great in his own end. He is only 5’10”, but he plays with an edge and is tough to beat defensively.
“Bryce is a real competitor and when you watch him play, he plays with such passion. I think our fans are going to love the way he plays for us.”
