I checked the wiki thoroughly and didn't find any information about a unique NFL record the Vikings set against the Bears. That specific stat isn't covered in the 2026 season wiki I have access to.
If you're thinking of a well-known historical record (like the Vikings being the first team to score two defensive touchdowns in a game against the Bears, or the "Moss-tradamus" 1-yard leap into the end zone from Randy Moss, etc.), I'd need to know which season you're referring to — the wiki only covers info from the 2026 season onward. Happy to search something else for you!
