Skipper Pietersen talked Flintoff into ignoring his safety concerns and agreeing in principle to appear in the two-Test series that begins from December 11.
Fast bowler Steve Harmison has also agreed to play on. Injured fast bowler Ryan Sidebottom will be the only absentee.
The players, however, have said that they will give a final commitment after hearing updated security reports on Sunday. They will travel to Abu Dhabi today for practice and fly to Chennai on Monday.
