Current manager Christian Chukwu, who is expected to deputisefor the foreign appointee, said training plans for the Nations Cup will not be finalised until the arrival of the new coach.
Bopara has taken Flintoff's place in the side for the fourth Test, in which England amassed 301-3 in the first day, and is likely to deputisefor him again for the final Test in Trinidad which starts on 6 March.
