The former Newcastle centre-half was a regular starter during the Old Lady's promotion from Serie B last season, but has made just one substitute appearance this term.
While injury problems have been partly responsible for the Frenchman's peripheral role, boss Claudio Ranieri appears to have doubts about his ability to cope with the pace of the top flight.
Lazio and Besiktas have both been linked with a move for Boumsong, but it now appears that Lyon are in pole position for his signature.
"We should complete a deal for Boumsong at the start of the week," Les Gones president Jean-Michael Aulas declared.
"In the next few hours we will meet with Juventus officials to come to an agreement."
Hajrá Lyon!
The deal is expected to be a loan deal that will be made permanent at the end of the season.
