Tendulkar, who is here as a goodwill ambassador for the Indian contingent, sat alongside Bach as the two watched the opening day of rugby sevens, which has made an Olympic return after a 92-year-absence.
"Wonderful spending time with Mr Thomas Bach, IOC president at #Rio2016 @olympics," tweeted Tendulkar after meeting the IOC chief yesterday.
Tendulkar is keenly tracking the performance of the Indian athletes in Rio and was seen supporting tennis players Sania Mirza and Prarthna Thombare from the stands.
Brett Gosper, chief executive of World Rugby, acknowledged Tendulkar's presence in the stands of the Deodoro Stadium along with Bach.
"Sachin was here for the whole session and loved it," Gosper said.
The International Cricket Council (ICC) has not yet confirmed whether it will push for the inclusion of Twenty20 format of cricket at the 2024 Olympic Games but Gosper feels Olympics would be a fantastic forum to expand the game of cricket.
"For them in cricket terms it's interesting to see rugby's journey into the Olympic and why that's an interesting proposition for cricket," said Gosper.
"I definitely think in terms of an expansive mentality, if that's where cricket's at, the Olympics would be a fantastic forum for them," he added.
Gosper also insisted that "cricket would be very good for the Olympics too".
