The 49ers and Packers released their injury reports and cornerback injuries are the name of the game heading into Sunday's game. We already discussed Casey Hayward's injury, which will cost him the game. The 49ers have their own nicked up cornerback in the form of Nnamdi Asomugha. According to the practice report, Nnamdi was a limited participant in practice with a collarbone injury. According to media reports from practice, Nnamdi was wearing a blue non-contact jersey.
During the preseason, Tramaine Brock seemed to have the early edge in the competition to be the team's third cornerback in place of Chris Culliver. However, Nnamdi moved ahead of him late in preseason. According to defensive coordinator Vic Fangio, Nnamdi moved ahead because Brock was dealing with an injury. However, in the final week, Fangio said that Nnamdi himself was dealing with an injury. It would seem that has carried over to game week.
There is no word on whether or not Nnamdi will play, but given that Brock has gotten so many reps in the preseason, and it seems Fangio is a fan, the team might very well be comfortable deactivating Nnamdi for Week 1. It is hard to tell yet what will happen, but we do know the 49ers will need all the cornerbacks they can muster.
Last season, the 49ers and Packers squared off twice. In the first game, the 49ers used a fair amount of nickel, and a whole lot of dime. Perrish Cox played as the fourth cornerback, and he appeared in the game for 76% of the defensive snaps. In the playoffs, the team went with a lot more nickel, but Cox still appeared as the dime back 31% of the snaps.
The 49ers once again have five cornerbacks, but Brock very well might have leap-frogged Perrish Cox on the pecking order. If Nnamdi can't go, Brock likely gets the play outside, with Rogers moving into the slot. When the 49ers go to their dime package, Cox would seemingly once again be that guy, even if Nnamdi is healthy. Cox does most of his work in the slot, and if they are facing four and five receiver sets, his skills would seemingly play better inside.
Whatever the case, it's going to be an interesting chess match of QB vs. secondary for both teams.
