Running back Kenneth Walker III of the Seattle Seahawks has been an effective fantasy option when healthy this season, ranking No. 18 among PPR running backs despite missing two games earlier this season.

Walker is getting steady involvement as a pass catcher with a career-best 38 receptions in just 10 games, and his seven rushing touchdowns have helped make up for a pedestrian 3.7 yards per carry behind a shaky offensive line.

Further, Seattle has a key NFC West game against Arizona in Week 14. But will Walker be available for the final week of the regular season in many fantasy formats? Let's take a look.

Walker (ankle, calf) practiced in a limited capacity on Wednesday but did not participate in Thursday's practice, which is rarely a good sign, especially considering Walker's injury earlier this season was an oblique.

In shallower leagues, managers rostering Walker may still have backup Zach Charbonnet available on waivers, which would be the most logical way to hedge against an absence. Otherwise, they'll have to look elsewhere for help at running back, which may be a challenge with six teams on a bye this week.

A backup plan would be wise with Seattle set to kickoff at 4:05 EST, meaning Walker might be ruled out after 1 p.m. games have locked.

RotoBaller has Walker ranked as the No. 15 running back option this week against an Arizona defense ranked in the 50th percentile against fantasy running backs. Even with a Seattle line that has struggled, Walker is still clearly a starting option this week, albeit only if he's healthy enough to do so.

It's a playable matchup for whichever Seattle back is getting the lion's share of the carries.
