Dixon left Saturday's preseason matchup with an apparent chest injury and is questionable to return, Jonathan Jones of the Charlotte Observer reports.
In his NFL debut last week, Dixon tallied three tackles against Baltimore. The Washington product has taken reps at both cornerback and safety for Carolina in the early going, but with a lot of uncertainty surrounding Dixon and his injury, it remains to be seen if he'll be able to squeak onto the roster by preseason's end.
Johnson (Achilles) was placed on the Panthers' reserve/NFI list on Monday, Steve Reed of the Associated Press reports.
Johnson also began training camp on the active/NFI list after undergoing offseason surgery to repair an Achilles injury suffered last season with the Patriots. Although no timetable was provided for his return, Johnson could theoretically resume playing after the first six weeks of the regular season.
Woods (foot) is inactive for Sunday's game in Miami.
The Bills will now go with an "interesting" starting receiver tandem of Marquis Goodwin and Justin Hunter, as their top three wideouts are all out on this one. It's certainly a good thing the team has the league's top-ranked rushing attack.
Williams signed with the Steelers' practice squad Wednesday.
Williams was let go by the Bills after he showed up this summer grossly out of shape and then received a four-game suspension for a violation of the NFL's substance abuse policy. However, he did score nine touchdowns for the Bills last season, so putting him on the practice squad and seeing what he can do seems like a good low-risk signing by the Steelers. Still, some other team could pluck him off there pretty quickly.
Reddick, who suffered a sprained MCL in practice Friday, was waived/injured by the Bills on Sunday.
The Bills didn't have much choice here with several other linebackers injured and reinforcements needed. If Reddick clears injury waivers, the Bills can then either place the him on IR or agree to an injury settlement with him.
Coach Rex Ryan said Monday that Listenbee, a sixth-round rookie out of TCU, still isn't ready to practice as he recovers from double hernia surgery, The Buffalo News reports.
Even though the Bills have been decimated at wideout all season, there's simply not going to be enough time for this year to be anything more than rehab and learning for the speedy rookie, who's incredibly raw but may also be one of the NFL's fastest players once he's back.
