Williams (knee) will not play Monday against the Steelers.
Williams failed to practice all week, which will culminate in his second missed game over the last four weeks. Rookie Khalil Herbert had already surpassed Williams as the clear-cut starter over the past two weeks, but the possible return of David Montgomery (knee) from injured reserve could complicate the backfield situation somewhat. More information regarding Montgomery's situation, and by default Herbert's, should arrive sometime in the afternoon Sunday.
