The defender joined the Foxes from Sporting Gijon in June but has opted to join Marcelo Romero's side, having played just four Premier League games
A short, forgettable spell at Leicester City for Luis Hernandez has ended with a move to Malaga.
After leaving Sporting Gijon, the Spanish defender joined the reigning Premier League champions on a free transfer in June, signing a four-year deal.
But the 27-year-old, having made eight appearances in all competitions, is already on the move again, exiting the King Power Stadium in favour of a return to La Liga.
A product of Real Madrid's academy, Hernandez's long throw helped to set up Marc Albrighton's strike against Club Brugge, the Foxes' first goal of their debut Champions League campaign.
