"This behaviour is completely unacceptable and damages the reputation of football and of our club," said Graz on its website after they had lost the first leg of the third qualifying round tie 2-0.

The linesman was hit and fell to the ground in the 78th minute of the game with blood pouring from his head.

After being treated by medics, he walked to the dressing room with his head bandaged. Sturm Graz added that the fan who threw the missile had been apprehended.
