The Burnaby, B.C., native was trying to win Canada's third wrestling medal of the London Olympics. Tonya Verbeek took a silver on Thursday, a day after Carol Huynh picked up a bronze.
Canada hasn't won a men’s wrestling medal since Daniel Igali captured gold in the men’s freestyle 69-kg class in 2000.
Gentry earned a spot in the bronze match by defeating Francisco Soler Tanco of Puerto Rico in the repechage. He then faced a tough opponent in Tsargush, the world champion in 2009 and 2010.
Gentry was a quarter-finalist at the 2008 Beijing Olympics. He's never won a world championship medal.
Gentry defeated India's Narsingh Yadav in the round of 16 before falling to eventual gold medallist Jordan Burroughs of the U.S. in the quarter-finals. Gentry got another chance to compete for a bronze medal because wrestlers who lose to the two finalists are granted a spot in the repechage round.
In the final, Burroughs defeated Iran's Sadegh Goudarzi, who got the silver medal.
Two bronze medals are awarded in wrestling, and the other went to Uzbekistan's Soslan Tigiev.
