Three players have been named in the England squad for the three-test series in Pakistan.
Broad is going to have a child in November and won't be on the tour.
Alex Lees missed out on a central contract despite playing 10 Tests for England.
Mark Wood missed the home summer through injury but is expected to play in the Test.
Ben Foakes is in the England squad for the Pakistan series.
Jacks and Livingstone are both uncapped at Tests.
Jack Leach, the only specialist spinner in the squad, is supported by two spin-bowling all-rounders.
England were short of spin options when Moeen Ali decided not to take part in the tour, while Matt Parkinson, who made his Test debut as a concussion sub at the beginning of the summer, has fallen out of favor.
Jacks averaged 54 with the bat and 17 with his off-breaks for the county champion. Livingstone hasn't played a first-class match in over two years.
When Lees was left of the central contract list, he appeared vulnerable.
He averaged 72 in the County Championship and played 17 Tests in the last year.
He could be in the way of Ben Duckett opening the competition.
Duckett was called up by England for the final Test after Bairstow broke his leg. There are other options to open, like Harry brook.
Wood is fit again after elbow surgery.
Despite being in England's Test squad over the summer, Matthew and Craig don't have a place in the squad. Broad didn't want to be considered.
Ben Foakes is the only specialist who can keep the ball in the ground.
England's first Test series in Pakistan since 2005 starts on December 1st in Rawalpindi, with matches in Multan and Karachi to follow.
After guiding England to six wins from seven Tests this summer, they will lead the overseas tour.
The last time England traveled to Pakistan was 17 years ago, when they lost a T20 series.
