McDonald's is bringing back the McRib. But unlike past years, fans of the saucy pork sandwich are going to have to wait to get their fix.

McDonald's will not roll out the popular pork sandwich in October, as it has it has in the past.

A memo obtained by Ad Age says it will be on the menu in time for the holidays in late December.

Advertising will also promote "quality pork" and a "unique taste."

The leaked memo says the late release is an effort at drumming up an end-of-the-year sales surge.
