Shields Hits Injured Reserve

Tuesday, Oct. 18

The Packers announced Shields was placed on the injured reserve and newly acquired running back Knile Davis has joined the active roster.

Mike Garafolo of NFL Network initially reported the move would happen, noting Shields' concussion did not subside as the team had hoped. Doctors want to make sure Shields, who has had five concussions in his career, is OK to play before he returns to the field, per Garafolo.

McCarthy Comments on Shields' Concussion

Friday, Sept. 23

"Talking with doctors this morning, they said he's making progress in the protocol," McCarthy told reporters.

McCarthy told reporters Shields worked out on Sept. 19, but he did not have an update on his progress.

McCarthy told reporters on Sept. 14 that Shields remained in the concussion protocol and that he did not have a further update.

"Any time any of our players is in the protocol and dealing with a concussion, it's a concern," McCarthy said on Sept. 12, per ESPN.com's Rob Demovsky. "That's why we'll evaluate Sam each and every day, and most importantly to make sure he's healthy and goes through the challenges of what he's dealing with."

Shields Has History of Concussions

Demovsky noted Shields has a history of concussions. He has now suffered three documented concussions in the NFL.

Shields has been injury-prone throughout his career, having never played all 16 games in any of his first six seasons. The 28-year-old missed four games last season, including each of the final three games and the Packers' playoff opener against Washington, with a concussion.

The Packers are accustomed to playing without Shields because of his injury problems, which allowed Quinten Rollins to get plenty of exposure.

"We've been through this," defensive coordinator Dom Capers said, per the team's official Twitter account. "We've got guys who are trained in multiple positions."

The Packers are fortunate to have one of the NFL's deepest secondaries, with Brent Rollins of Pro Football Focus ranking Green Bay as the third-best group overall in 2015.

Shields ranked second among Green Bay cornerbacks on that list behind Casey Hayward, and Damarious Randall tied for the team lead with three interceptions in his rookie season.

Depth has improved for the Packers secondary, with young players such as Hayward and Randall playing well. Shields is still an integral part of the defense, but it is better equipped to handle his health woes than ever before.
