Before the 31-year-old hurt his hamstring and underwent surgery, the center-back joined the Owls in October and played four times for the Sky Bet Championship team.
Flint returned to Wales to complete his recovery and was not expected to be completely fit until February, but will not play this season again on Wednesday. “The Owls can confirm that Aden Flint has returned to his parent club Cardiff,” read the club’s official statement. “In October, the towering defender joined the Bluebirds on Wednesday on loan and played four games for the club. “We want to thank Aden for his services and wish him all the best for the future.”
