EA has released a revised roster update #4 which originally came out on October 23rd, the details of which you can find here.
It seems likely that the motivation to do so came from having a few players with the incorrect race, such as the newly added Koren Robinson. This gave them the opportunity to make a handful of other changes that occurred too late to get them in before, such as moving Ronnie Brown to the IR and replacing him with the recently signed Samkon Gado.
