Impact: Players tweak their deals fairly often, but in the case of Williams, it is notable since there had been whispers that his previous contract could lead to the Panthers potentially dangling him in trade talks.

In any case, the move ensures that Williams will stick around in Carolina to share the team's backfield with Jonathan Stewart and fullback Mike Tolbert.
