Somers is reporting that the injury is actually plantar fasciitis, which means that the Cardinals could possibly elect to place Groves on I.R. with only two games remaining in the season. Groves was seen sporting a walking boot in the locker room after the game.
If Arizona indeed decides to shut him down, the Cardinals will be left with Reggie Walker and rookie Zack Nash to take over the outside linebacker role in their 3-4. First-stringer O'Brien Schofield was placed on season-ending I.R. in early November after his left ankle injury required surgery.
Groves has fared relatively well in his first season with the Cardinals, compiling 44 tackles, four sacks and one blocked kick across 14 games. Groves' sacks were actually his first since his 2008, his rookie season with the Jacksonville Jaguars.
