I don't think this is accurate. There is the active NFI and the reserve NFI.
According to DaSilva, "Sean McVay shared on Sunday that Robinson is on the
active/non-football injury list and won’t be back until “some point this season."
"For the active NFI, "There are two types of NFI designations: the Active/NFI designation leaves the door open to returning to practice once the player is medically cleared. Meanwhile, the Reserve/NFI designation is for players who will not return to the active roster during the regular season. With the “Active” tag, players count against the roster max, whether it’s the 90-man or 53-man version. With the “Reserve” tag, they do not."
