Walker missed Seattle’s Thanksgiving tilt against the division rival 49ers last Thursday and now starts the week off on the wrong foot heading into their second Thursday matchup in a row at Dallas. Walker has a history of core injuries, so it will be imperative for him to get onto the practice field today or tomorrow for there to be any chance of him playing this week. If Walker should miss a second week with his oblique injury, rookie RB Zach Charbonnet would likely reprise his role from last week as the Seahawks’ lead running back. The production wasn’t there last week in a blowout loss to the 49ers, and another tall task stands ahead of Charbonnet this week against Dallas, who are allowing the 6th-fewest fantasy points to running backs on the season. Charbonnet would profile as a high-RB3 in that matchup with some upside.
