Jurgen Klopp Dortmund manager Champions League touchline suspension extended after being sent to the stands against Napoli

Borussia Dortmund manager Jurgen Klopp will be consigned to the stands for his side's Champions League clash with Arsenal after his touchline ban was extended for another game.

UEFA had initially suspended Klopp for one match for clashing with the fourth official during last month's 2-1 defeat to Group F foe Napoli. After reviewing the incident again on Wednesday, the European governing body has decided to double the length of the ban, meaning Klopp will not be on the touchline for the game at the Emirates Stadium later this month.

Klopp has already publicly apologized for his antics, admitting that he behaved "like a monkey," and Dortmund could yet decide to appeal this latest ruling.

Dortmund, which routed Olympique de Marseille 3-0 at Signal Iduna Park on Tuesday, faces group leader Arsenal in a crunch clash at the Emirates on Oct. 22.
