Walker signed a contract with the Saints on Tuesday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Walker played for New Orleans last year but didn't make an active roster in 2018. His signing comes on the heels of Sheldon Rankins' (Achilles) move to IR. Walker will serve as a backup defensive tackle behind David Onyemata and Tyeler Davison as the Saints look to take down the Rams on Sunday.

Walker has signed with Buffalo, Chris Brown of the Bills' official site reports.

EDGE Analysis

Walker has been floating around the league since 2012 and actually started four games for a strong Rams program in 2017. He'll try to make the team as a depth defensive tackle, as the Bills are already well set at the position with starters Kyle Williams and Star Lotulelei, along with high draft pick Harrrison Phillips.

Walker and the Rams agreed to a contract on Wednesday, Gary Klein of the Los Angeles Times reports.

EDGE Analysis

Walker signed with the team back in March, but was ultimately released in June. With Aaron Donald still holding out, he will join a plethora of defensive tackles looking to land a spot on the final roster. The 27-year-old will look to impress for the remainder of camp in order to earn a depth role on the line.

Walker was released by the Rams on Wednesday, Adam Caplan of ESPN.com reports.

EDGE Analysis

Walker signed with the Rams back in March after spending the past two seasons with the Lions. Only 27, the defensive tackle has a good shot of winding up on another roster before training camp.

The Rams signed Walker on Thursday, Adam Schefter of ESPN reports.

EDGE Analysis

Undrafted in 2012, Walker spent the first three seasons of his career with the Saints, before logging a two-year stint in Detroit. Overall, he's totaled 63 tackles (38 solo), 3.5 sacks, one forced fumble, and one fumble recovery across 42 games. As a member of the Rams, Walker will serve as a rotational piece behind starting defensive tackles Aaron Donald and Michael Brockers.

Walker (calf) is active for the Lions' Week 3 matchup Sunday against the Packers, MLive.com's Kyle Meinke reports.

EDGE Analysis

Walker only put in one full practice during the week, but he's still expected to fill his usual starting role at one of the defensive tackle spots. He's recorded six tackles and no sacks through the Lions' first two games.

Walker (calf) is questionable to play in Week 3 against the Packers.

EDGE Analysis

Walker began the practice week by watching Wednesday's session from the sidelines, but his calf condition improved enough for him to be a full participant Friday, making it appear as though he'll be able to play Sunday.

Walker re-signed with the Lions, inking a one-year deal on Thursday, Justin Rogers of MLive.com reports.

EDGE Analysis

Walker signed a one-year contract with the Lions last season and will now remain with the team for at least another year. In 2015 he played in four games, recording nine tackles.

Walker (leg) is having surgery to repair a broken fibula, and he will be placed on injured reserve, NFL.com's Ian Rapoport reports.

EDGE Analysis

Walker and Haloti Ngata (calf), the Lions' starting defensive tackles, both suffered injuries during Monday's loss to the Seahawks. Ngata's injury doesn't appear nearly as serious, so the Lions may only need to replace one starter. Caraun Reid and Gabe Wright figure to see more snaps.

Walker was carted off the field with a left ankle injury Monday night, Tim Twentyman of DetroitLions.com reports.

EDGE Analysis

He's not expected to return from the game, and considering the amount of pain he appeared to be experiencing, Walker could miss more time than that.
