With the championship round of the fantasy football playoffs underway, owners are checking the latest injury reports on two key starting running backs, Rhamondre Stevenson and Kenneth Walker III, who are listed as "questionable" heading into Sunday's action. If either of these RBs are ruled out for Isaac Seumalo Jersey Week 17, it will have a big effect on start 'em, sit 'em decisions for the championship round.Below, we'll give you the latest news on these RBs and break down how their injuries could potentially affect the Week 17 fantasy landscape.WEEK 17 INJURY UPDATES: | WEEK 17 FANTASY PICKS: | | UPDATE:ESPN's Dan Graziano that Stevenson will be "OK" to play on Sunday against Miami.UPDATE 2:Stevenson is officially ACTIVE.Stevenson (ankle Austin Watkins Jr. Jersey ) against the Dolphins. The second-year running back practiced in a limited fashion this week and has been dealing with a nagging ankle injury for the past month.Stevenson is coming off a rough performance against the Bengals, who held him to 30 yards on 13 carries and two receptions (six targets) for three yards. It's po sible that he's being affected by the sore ankle, but he still gets enough touches to be viewed as a must-start. He will look to Landon Dickerson Jersey bounce back against a Dolphins defense that allows the 10th-most fantasy points to RBs this season. The Patriots will also have Damien Harris (thigh) back in the fold, who could take away a few snaps from Stevenson on Sunday. However, Harris should be viewed as a Wilbert Montgomery Jersey flex in Week 17 if Stevenson plays. If Stevenson is a surprise scratch, Harris would bump up to a high-end RB2.WEEK 17 PPR RANKINGS: | | | | | UPDATE:Walker is officially ACTIVE.Walker III (ankle) ahead of Sunday's game against the Jets. The rookie running back was a limited participant on Thursday after not practicing on Wednesday.Fantasy owners should not hesitate to start the young running back on Sunday. Walker has been dealing with this injury for a couple of weeks but played considerably well last Matt Leo Jersey week against the Chiefs, racking up 107 yards on 26 carries, which was his most carries since Week 9 against the Cardinals. Walker has a tough matchup on Sunday, as the Jets' defense allows the ninth-fewest fantasy points to RBs this season, but he's still a must-start. If he's a surprise scratch, DeeJay Dallas would have high-end flex appeal.
