The Old School Ref: When Tech Trouble Takes Over The Premier League's referees took an unusual step last Sunday at Stamford Bridge, abandoning their high tech communication packs in favor of a more traditional approach to officiating.
For 45 minutes, the referee and his team relied on shouting and hand signals to communicate.
The absence of radio communication was due to a technical issue with the battery packs or link, which has occurred before but never resulted in such a drastic solution.
