Buffalo Sabres goaltender Aaron Dell recently became the first NHL netminder in a long time - likely since 2007 - to receive a suspension from the league for on-ice conduct. It’s incredibly rare that a goaltender receives supplemental discipline like this, and there are genuinely only a small handful of examples to point to throughout history.
At the NHL level, you may think of Jamie McLennan, who was suspended for five games following an incident in a 2007 playoff game. He was playing with the Calgary Flames at the time & slashed Johan Franzen first in the leg (twice), and then in the stomach.
