Farah recovered and overtook Kenya's Paul Kipngetich Tanui to repeat as the Olympic 10,000m champion.

Rupp, who finished fifth, took responsibility for the collision after the race.

"I bumped into him, there was a lot of pushing and guys slowing down in front of me," the American told Jenna Fryer of The Associated Press. "Obviously I didn't want it to affect the race at all, and wanted make sure he was OK.

"I told him to get behind me after that, (to) help lead him back up there. I'm just thankful it didn't affect the outcome."
