Greg Rutherford has been forced to withdraw from this month's World Indoor Championships in Portland due to illness.
The Olympic and world long jump champion is continuing to recover from a chest infection and a minor hamstring strain.
British Athletics Performance Director Neil Black said: "Greg is really disappointed not to be able to compete in Portland, but his body reacted harder than expected to this week's training.
"Defending the Olympic title is obviously Greg's main focus for 2016, so he has sensibly decided not to take any risks and to end his indoor season here.
"This will allow him the opportunity to concentrate on being in the best shape possible going into the outdoor season and ultimately Rio."
It is the latest blow to Rutherford's Rio preparations after he was forced to miss last month's British Indoor Championships and Glasgow Grand Prix.
He had started the year in encouraging form after jumping 8.26 metres in Albuquerque to lie second in the current world rankings.
