I wouldn't draft him in a redraft at all. I'm not wasting a roster spot on someone that may or may not contribute until 9 games into the season. This isn't a team that will immediately thrust him into a starter role upon coming back. Chubb is a really good RB and isn't going to give up a ton of carries to him. If I was a Chubb owner, I'll probably just wait for someone to drop him to handcuff him.
