Briand, 27, was not present at Lyon’s training centre Tola Vologe this morning, which is enough to suggest that the player is leaving les Gones for Monaco.
L’Equipe understands that the player was undergoing a medical at Stade Louis II ahead of his move to the Principality.
The Ligue 2 side have an option to buy the forward outright at the end of the loan and they are almost certainly going to exercise the clause.
Briand was recently linked with a move to Besiktas, but he was ultimately tempted by the ambitious project that is in place at Monaco.
The French giants, who are widely tipped to gain promotion to Ligue 1 at the end of the season, are also set to wrap up a deal for Ajaccio defender Carl Medjani.
