Tom Daley's synchro platform partner Peter Waterfield has pulled out of next week's European Championships due to a neck injury.
Waterfield did not join the British team when they travelled to Eindhoven on Friday as a precaution to ensure his fitness for this summer's Olympics.
The injury is a blow to his preparations for the Games, however, with the European Championships the last international meet before London.
"I didn't go to the Europeans as i have a neck injury, so had an injection in it yesterday and have another on Thursday," the 31-year-old, who won silver in the synchro platform at the 2004 Athens Olympics, wrote on his Twitter page.
"To make sure I'm all good for the games!"
Waterfield missed two months at the start of the year with side complaint but returned to take a bronze medal in a stunning display in the individual platform at the World Cup in London.
His performances alongside Daley since have been mixed after receiving criticism following their seventh-placed finish at the February World Cup.
They followed it with silver in the second leg of the World Series before rounding out the competition with a third placing in Tijuana, Mexico late last month.
