According to Boxrec there was a fight for the French lightweight title over 15 rounds between champion Georges Papin and challenger Leon Poutet at Salle Wagram(Paris) on 1921-12-16. It ended in a draw. There are no newspaper reports to verify this fight. Actually there is a report in Le Matin 1921-12-17 (page 3) which indicates that the fight didn't take place at all, if my limited knowledge of French serves me right.
