The father of French rugby international Imanol Harinordoquy brought a French club match between Biarritz and Bayonne to a halt after running onto the pitch to defend his son.
Harinordoquy's father came down from the stands early in the match and squared up to Bayonne flanker Jean-Jo Marmouyet after his son got involved in a punch-up.
Harinordoquy senior's sense of family loyalty was brought to an abrupt halt by Bayonne first five Benjamin Boyet, who tackled him to the ground.
