Ajax Amsterdam and Feyenoord’s 2-2 draw has been marred by supporter ill-discipline with the latter’s Daryl Janmaat struck by a bottle.
In the 37th minute of the traditionally intense Eredivisie clash on Sunday, defender Janmaat and winger Wesley Verhoek corralled Ajax’s Ryan Babel in the corner.
As Babel won a throw in, Janmaat was hit in the head by a bottle and fell to the ground but was able to play on.
The 23-year-old Dutch defender suffered no serious consequences.
The bottle was thrown from within the Feyenoord supporters end of their home ground, De Kuip, in Rotterdam.
