Olympic long jump champion Greg Rutherford has pulled out of this Sunday's Anniversary Games in London.
Rutherford, 27, who won gold on Super Saturday at the Olympics two years ago, has struggled recently with a knee injury.
He was forced to pull out of last weekend's Diamond League meet in Glasgow, but has revealed this withdrawal is precautionary.
"Sadly I wont be jumping this weekend in London," the athlete wrote on Twitter.
"Precautionary decision with the Commonwealth Games being so close."
The Commonwealth's begin on July 23, with Rutherford expected to challenge for the title.
The Milton Keynes athlete set a new British record jump of 8.51 metres earlier in the year and has consistently broken the 8m barrier in competition.
His biggest challenge in the Games may come from fellow Englishman, Chris Tomlinson.
Tomlinson previously jointly held the record with Rutherford, before the latter leapt to that huge 8.51m.
