England currently play seven Tests and nine one-dayers each summer but the structure could be changed in 2006.

"We must play more one-day cricket but that doesn't mean we must play more cricket," Fletcher told BBC Sport.

"We're going to have to look at replacing the odd Test match here and there with a substitute of four one-dayers so players have decent breaks."

England won all seven Tests this summer against New Zealand and West Indies.

But they are currently eighth in the one-day rankings as they prepare to take on India in a warm-up series for the ICC Champions Trophy.

Only minnows Kenya have played less than England's 17 one-day matches in the last 12 months, which count for the International Cricket Council rankings.

Pakistan lead the way with 33 and every other team has played at least 20.

The three-match NatWest Challenge series -- with India the opponents in the second year it has been held -- was part of a Fletcher initiative to increase the number of games.

But the coach repeated his warning about the danger of player burnout if the schedule becomes too congested.

"We want to play more one-day cricket, we've got a lot of Test cricket and players have got to have a break," he added.

"Somewhere a fix has to be made and I feel the area we have to look at is play more one-day cricket and play an odd Test match less."
