Has anyone been "guaranteed" a Super Bowl ring because they played for both teams during the season?

I was reading this answer to the question “Who gets Super Bowl rings?” which says

Also, in some cases, players traded during the season will get them too, if they suited up and played during they regular season. This is also by ownership’s decision

Was ever a time when a player was guaranteed a Super Bowl ring because they are in the final game but they started the season for their opponents team?
