In the 1949 Tour de France, Callens was leading the general classification after he won stage 3, finishing in Boulogne-sur-Mer.

The next stage, Callens started with an unofficial yellow jersey, and lost the lead to Jacques Marinelli.

Callens was invited there, and finally got his yellow jersey, 45 years late.
