As the tweet went on to say, and as we reported after the surgery, Carroll previously said he expected Walker back for Week 1, so that seems like a potentially significant update that doesn't sound great for fantasy owners. Walker is missing valuable time with the team and so it looks like Penny will have much of the lead back work with Homer and Dallas serving as change of pace or passing down backs.
SEA RB Travis Homer - Week 1 Fantasy Football Outlook
Week 1 vs. Denver Broncos
Travis Homer should be the primary backup behind Rashaad Penny this week against the Broncos with rookie Kenneth Walker out with a hernia injury. Homer is a nice change-of-pace back who averages 5.9 yards per carry for his career. However, he's unlikely to get much work in this one behind Penny, and the Broncos ranked seventh in aFPA to opposing running backs last year. Homer can remain on waivers for as long as Penny and/or Walker are healthy.
