Rick got a stone against his head after the Frisian derby and was seriously injured. ‘Half his head was crushed’

Unsuspectingly, Rick Folkers and his brother-in-law Perry van der Linden (28) walk across the Cambuurplein in Leeuwarden on Sunday after the game between Cambuur and Heerenveen. Despite the loss of Cambuur, Folkers enjoyed his first visit to the Cambuur Stadium. The two have not experienced much of the disturbances surrounding the duel, until it suddenly goes completely wrong.
