The 23-year-old has only made four appearances this season for the Magpies for a total of 128 minutes, according to Transfermarkt.
Despite purported interest from Brighton, no move materialised in the summer, however, seemingly due to manager Rafael Benitez wanting to keep him on board for the time being as he was not guaranteed a replacement, according to the same outlet.
With academy graduate Sean Longstaff having penned a long-term deal at St James' Park, it appears as though Benitez will look to draft him into action, potentially leaving the door open for Hayden to leave in January.
Over at Bournemouth, the management and players are reeling from the long-term injury to Lewis Cook with a ruptured anterior cruciate ligament, expecting the midfielder to be out for up to nine months.
Although not exactly a like-for-like replacement, Hayden has a defensive element to his game much like Cook while also providing forward impetus - though the Magpies man is more of a through-ball or long shot kind of player, while Cook is more of a dribbler.
There might be some tactical tweaking needed from Eddie Howe and his backroom team, but in Hayden they would be getting a young player with a lot of potential - and from a geographical perspective, it would enable the player to be closer to the south-east.
