If you were a mostly ignorant sports fan like me, you would have searched for the meaning of this fancy sounding French word, right after Sushil Kumar's bronze medal. How can someone who lost in the first round get a medal --- Repechage provides a way. It means (re-fishing) or to be rescued. So a bronze medal was rescued for India :) However, this does not take away anything from Sushil Kumar who absolutely deserves this for coming through from nowhere with very poor training facilities. I wish we could have invoked repechage for tennis (mahesh-paes) for a bronze for them?
Then of course you have boxing where two bronze medals are allotted to the losing semifinalists (I am not complaining). Just checking to see if we can extend this to other sports. The reasoning behind this is that the losing semi-finalist could be sufficiently injured by a better opponent to prevent him from sparring again soon afterwards.
