It doesn't look like Whalen is going to be ready for Week 1 against the Rams. Gehlken added Whalen could be a candidate for injury settlement. The Raiders just traded Ryan Switzer to the Steelers and Whalen was among those battling for the slot receiver job.
BAL WR Seth Roberts - Week 6 Fantasy Football Outlook
Week 6 vs. Cincinnati Bengals
Seth Roberts has only been targeted 10 times so far this season, but his playing time has increased. He’s been involved in over 60% of the team’s offensive snaps in three consecutive weeks. While it’s good to see him on the field, his lack of production makes it hard to trust him. He failed to catch either of the two balls thrown his way last week against the Steelers, and he should remain on waivers for the foreseeable future.
