Steward has been placed on injured reserve due to a back injury suffered in Sunday's win over Houston, BuffaloBills.com reports.
Starter Nigel Bradham may not be able to make it back from his ankle injury this week. If that doesn't happen, the Bills would be down their top two guys at the inside linebacker spot next to Preston Brown.
Williams (hamstring) is competing for snaps at the nickel position in OTAs, Joel Erickson of the New Orleans Advocate reports.
Williams lost his entire rookie season after suffering a torn hamstring during training camp last year. Now that he's healthy, the 2015 third rounder will have the chance to show why he was taken so high in the draft. Keenan Lewis (hip) and Delvin Breaux look to have the starting cornerback positions locked down, so Williams will compete with Damian Swann and Kyle Wilson for the nickel role, playing primarily in passing situations. Along with the third corner slot, Williams will likely be one of the team's primary backups, seeing extra time in the event of any injuries to the secondary during the season.
Jordan (back) practiced without limitations Thursday, Larry Holder of the New Orleans Times-Picayune reports.
Jordan underwent back surgery in February and wasn't expected to rejoin the team until training camp. However, Jordan was much farther ahead in his recovery than expected and was able to return to the practice field in full for the team's OTAs on Thursday. Jordan is coming off a 10-sack Pro Bowl season and with the back injury finally behind him, he'll have the chance to improve on his numbers.
Lewis underwent hip surgery Monday, The New Orleans Advocate reports.
Lewis was placed on season-ending injured reserve recently due to hip and knee complications, and had surgery on his hip labrum Monday to correct that ailment. The veteran will now aim to get healthy ahead of next season, while the Saints' porous defense tries to at least finish this season respectfully.
Wright (undisclosed) will be placed on injured reserve this week, NFL Network's Rand Getlin reports.
Wright opened the season as a starter, but his Week 1 injury gave Chris Conte a chance to shine. Hobbled by injuries for much of the year, Wright finished with just 25 tackles and three passes defensed in nine appearances. He is under contract for 2016, whereas Conte's deal expires at the end of the season. The Bucs might also opt to look outside of the organization for a starting safety to pair with Bradley McDougald.
