The Venezuelan men's 4x400 relay team successfully appealed a ruling disqualifying it from the competition and will compete in Friday's final, Olympic officials said.
Arturo Ramírez, Alberto Aguilar, Albert Bravo and Jose Melendez had initially been disqualified for obstructing the Australia squad's way in Thursday's first round.
The Venezuelan track athletes protested, saying they had run a clean race and deserved to qualify after finishing fourth in Heat 2 with a time of 3:02.62.
The jury for the competition examined the video and decided to overturn the disqualification, saying the contact that occurred was within the acceptable range for a baton pass.
Previously, the Jury of Appeal had refused to accept a challenge filed by the Dominican 4x400 team against its disqualification in that same heat.
The Dominican quartet of Gustavo Cuesta, Felix Sanchez (gold medalist in the 400-meter hurdles), Joel Mejia and Luguelin Santos (silver medalist in the 400 meters) were disqualified for passing the baton outside the take-over zone.
Runners from the Bahamas, the United States, Trinidad and Tobago, Britain, Cuba, Belgium, Russia, Venezuela and South Africa will compete in Friday's 4x400 final.
