On 30 August 2009, Witsel sparked controversy when he broke Marcin Wasilewski's leg by stamping on his ankle during the match between Anderlecht and Standard. Following the tackle, Witsel protested the red card, claiming that it was an accident without intent, before being sent off the pitch. He soon apologised, but was the subject of criticism from several media outlets and numerous death threats from angry Anderlecht and Poland fans. The initial ban until 23 November by the Belgian Football Association, was later reduced on appeal to eight matches.
