The games v Chesterfield, Plymouth and Mansfield have been moved to avoid City playing at the same time as the Welsh rugby team in the Millennium Stadium.
The Huddersfield fixture is changed to allow an extra day break after the Boxing Day fixture. City would have played Thursday (26th), Saturday (28th) and Wednesday (1st, Jan). Now there is a more even gap with Thur / Sun / Wed.
The Northampton and Bristol changes will be aimed at restricting flare ups from rival supporters. There was some confrontation at Northampton last season and at Bristol. The clash at Ashton Gate has been moved from a bank holiday Monday afternoon to the day after and made an evening kick off.
