Williams was in considerable pain after the game. The injury occurred when he was hit from behind by his own player while chasing down a receiver.
When a player carries the his arm of the field the way that Williams did, it is always a worry, and the replays of the hit didn't ease any fans' minds as his arm looked to be jarred and contorted the wrong way.
To this point, it is unknown how long Williams will be out for, but the Packers will be hoping it is not as serious as it looks because he is the team's best corner right now.
That is not to say that the team cannot cope without him, should it need to.
Replacing Williams in the lineup will be made easier if Mike Neal can get back on the field. The Packers played mostly nickel coverage last night with only two down linemen. Neal is expected to be Cullen Jenkins' replacement in Green Bay, but was injured last night.
The fact that the Packers played that much nickel and have such a deep group of cornerbacks will make dealing with the Williams loss much less difficult. Everyone knows what to expect from Charles Woodson, while Sam Shields is a proven player after playing a starring role in last season's Super Bowl run.
Jarrett Bush replaced Williams last night and it's not the first time that he has come in effectively in relief. Bush made a lot of plays in last year's Super Bowl after Woodson went out of the game injured.
If the Packers do struggle in the back end, they do have the ability to hide those flaws with pressure.
Pressure is the perfect way to ease the concerns with coverage, and with Dom Capers' complicated blitz schemes being called, the Packers have the ability to confuse quarterbacks and prevent them from picking on their corners.
The Packers will look to Clay Matthews in order to crank up the pressure, as they used him a lot more in coverage last night, as opposed to getting after Drew Brees through Zach Strief. Matthews has to carry the load upfront with Cullen Jenkins gone.
Matthews has two outstanding linebackers inside of him with A.J. Hawk and Des Bishop excelling last night. However, neither of those players or Erik Walden are impressive getting after the quarterback on a consistent basis.
The Packers will need to use confusion and rely on B.J. Raji and Matthews to command double teams because they do not have the greatest individual pass rushers on the roster.
Should Williams miss a lot of time, the Packers will be able to continue to win, but it will also be a significant loss and a problem that needs to be worked around rather than overcome.
