The Bengals play again Thursday. There is no practice for them next week. My guess is they are practicing him this week for a potential start next Thursday. I don't see them starting Burrow on Sunday after being out for several months and then playing him again four days later. Hey may be activated by Sunday, but my guess is his first game is Thanksgiving which is way ahead of schedule from where they expected him.
I cannot see the Bengals playing Burrow twice in four days coming off a significant injury.
