A freak accident which saw French long jumper Salim Sdiri speared by a javelin overshadowed the IAAF Golden League meeting in Rome on Friday.
Sdiri's injury is not thought to be serious
Salim was crouching in the warm-up area when a wild throw from Finland's Tero Pitkamaki hit him in the upper body.
He was rushed to hospital but his injury was not serious and he returned to his hotel room early on Saturday.
Meanwhile, world record holder Asafa Powell made his comeback from injury by winning the 100 metres in 9.90 seconds.
Powell, who had not raced an individual 100 since suffering a groin injury on 23 June, recorded the second best performance of 2007, behind the 9.84 mark set by Tyson Gay last month.
"It was my first race after the injury and I am happy with the time and the way I ran.
The javelins were falling not too far from our area and I saw one landing near my foot
"I eased up at the finish as I did not want to put pressure on after the injury," said Powell.
Then he predicted: "The clash between me and Tyson Gay will be one of the showdowns of the year."
Sdiri, who is now a major doubt for the World Championships which start on 25 August in Osaka, Japan, admitted that he had been ill at ease because the men's javelin and long jump events were taking place at the same time.
"I had my worries. We had begun our competition and the javelin throwers were warming up," he said.
"The javelins were falling not too far from our area and I saw one landing near my foot. I couldn't really see it arriving as my back was to it."
In the women's 100m hurdles, world champion Michelle Perry set the fastest time of the year by winning in 12.44 seconds.
The men's 5,000m also produced the best performance of 2007, with Sileshi Sihine of Ethiopia out-sprinting Kenya's Eliud Kipchoge to win in 13 minutes 01.46 seconds.
And Paralympian Oscar Pistorius warmed up for this weekend's 400m showdown with Olympic champion Jeremy Wariner by finishing second in the B race.
Pistorius, who was born without the fibula in both legs and had his limbs amputated below the knee at the age of five months, overhauled the field to finish in 46.90 seconds, 0.18 seconds behind winner Stefano Braciola.
Britain's Michael Rimmer finished just outside the top three as he came a creditable fifth in his first 800m appearance on the Golden League circuit.
