Greg Rutherford has pulled out of this weekend's Indoor British Championships through illness - but said he still plans to compete at next month's World Indoor Championships in Portland.
The Olympic long jump champion, who was forced to miss last Saturday's Glasgow Indoor Grand Prix with a small muscle tear, has withdrawn from the Sheffield meeting after suffering a chest infection.
Rutherford said on Twitter: "Sadly I wont be jumping in Sheffield this weekend. I've had a chest infection on top of the small injury so its a no go.
"But the aim is still the World Indoors. It took 2 jumps to break the British indoor record & Im aiming for all 6 jumps in Portland ;)."
The 29-year-old leapt out to 8.26 metres in Albuquerque earlier this month and lies second in the world rankings.
The W orld Indoors take place in Portland, Oregon, from March 17-20.
