Need some Game Used laundry Tag history buffs to help me pinpoint a jersey! Whether or not it's "Game Used" (It is certified by Panini as being game used and signed directly on the card by Bo Jackson...)

I am unsure of the history... it's a piece of a RIPON laundry tag (who took over Sand Knit in 1992) after Bo got injured...although it does say "Designed Exclusively for the Los Angeles Raiders" also which means it has to be before 1994 (when they converted to the Oakland Raiders) Is it possible RIPON made game used jersey's for the Raiders before 1992...or are all of Bo's jerseys Sand Knit?
