There could be an unofficial bounty. One that isn’t actually stated (ie. money on board).
Back in the day, after a Jacob Kindl clean hit on Robbie Drummond that left him concussed (head hit glass), it was “Get Kindl Night” in London. It was obvious from a mile away what was happening. Multiple attacks on Kindl all night long.
A little further back in the day, after a Ryan Thompson sucker shot on Derek Roy that left Roy with an eye injury, it was “Get Thompson Night” during a playoff game in Guelph. What was happening was also obvious from a mile away. Multiple attacks on Thompson all night long.
Both scenarios were something to see really. I’m not saying there was an official bounty put on Kindl or Thompson, but make no mistake, it was retribution night in both instances.
