Lewis has featured just five times in the Premier League this season and has been reduced to a bit-part player role at Newcastle.
The Magpies are set to sign left-back Matt Targett and Dan Burn from Aston Villa and Brighton today and already have Paul Dummett and Javier Manquillo in the squad.
He is set to fall further down the pecking order at Newcastle with suggestions he could leave before the window closes tonight.
It has been claimed that Newcastle are now open to listening to offers to loan out Lewis in the coming hours.
The full-back has been attracting interest from clubs in the bottom half of the Premier League and the Championship.
Newcastle are now considering whether they would be prepared to potentially strengthen a Premier League rival today or let him join a club in the Championship.
The Magpies are likely to want to see Lewis play on loan in the second tier of English football.
