Olympic hero Mo Farah was beaten in the 5,000m race of the Eugene Diamond League meeting in Oregon.
Farah finished second behind Kenyan Edwin Soi, who won the race in a time of 13 minutes 4.75 seconds after out-sprinting the double Olympic champion in the final 200m.
This was the 30-year-old's first Diamond League event of the season and he chose to compete in the 5,000m instead of the 10,000m after being hit by a stomach virus.
Elsewhere, Christine Ohuruogu finished fourth in the 400m, Greg Rutherford was third in the long jump and Perri Shakes-Drayton came sixth in the 400m hurdles.
