FDJ's Geniez was caught on camera confronting Dupont after stage three of the Giro in Arnhem, where both riders finished down on the winner Marcel Kittel because of a late crash.
We're not sure what the scuffle was about, but Geniez looked pretty annoyed with his fellow Frenchman, grabbing Dupont by the scruff of the neck in front of quite a few Dutch fans.
A motorbike rider eventually steps in and Geniez wheels off, leaving Dupont looking a bit shellshocked.
Geniez was fined 200 Swiss Francs by the men in charge over the incident for 'improper conduct', although I'm sure the 1-37 he lost on the stage will hurt him more than the financial penalty.
