Sanf, good catch on the Joey MacDonald! I also dug a little deeper into Pat Jablonski and after much searching was able to find he did dress in at least one NHL game with the Toronto Maple Leafs.

Not Felix Potvin. Damian Rhodes gets the nod for Toronto, with ex-Windsor Spitfire Pat Jablonski backing him up. Potvin, who has played all 11 Leaf games, stays in Toronto to rest up for Saturday's game with Los Angeles.
Rhodes played the game against Detroit and I found a photo of Jablonski dressed as the backup so its 100% certain he was backup in this game.
Pat Jablonski spent a lot of time with the Maple Leafs in the shortened season but his role was reduced to third goalie behind Rhodes and Potvin. Its possible Jablonski dressed in a couple more games because another article from that season quotes Pat Burns as saying he planned to rotate backups Rhodes and Jablonski.
Thanks for brining up Garrett. I've read about this story before but Garrett doesn't make my cut because, as the article mentions, he doesn't suit up. I have to draw the line somewhere and my criteria is that the goalies have to be signed, dressed and on the bench ready to step into action. I am, however, putting together a small list of goalies who have made it this far. There are a few, like Ray Whitney's dad, who fall into this category of "third string backup" who were there but not technically part of the team.
