"Congratulations to sushil kumar!! First indian to win back to back individual medals! a hallmark of a great athlete!!" he said.
Joining Yuvraj was Suresh Raina, who said, "Sushil's silver is no less than Gold. What a fighter! Heard he was dehydrated before his fight. Great feat to win at consecutive Olympics."
The 29-year-old Sushil, who was India's flagbearer in the opening ceremony, lost to Japanese Tatsuhiro Yonemitsu in the gold-medal bout.
With the addition of Sushil's silver medal, India completed their engagements in the 30th edition of the Olympics with a record haul of six medals -- two silver and four bronze -- but the gold medal could not be won by anyone.
In Beijing, India had won one gold and two bronze medals.
Sushil came into prominence after winning the World Cadet Games in Poland in 1998. This was soon followed by the Asian Junior Wrestling Championship in 2000 and the Arjuna Award in 2007.
He became a household name by coming out of nowhere and landing India a bronze at the Beijing Games. It was a testament to his mettle that he was given the chance to be the coveted flag-bearer of the Indian contingent at the opening ceremony of the London Games.
From training in mud pits to sleeping with 20 other boys, it was a giant leap for the grappler.
He started training at the Chhatrasal Stadium's akhada under the guidance of pehalwans Yashvir and Ramphal and later by Arjuna awardee Mahabali Satpal Singh and then at the Railways camp by coach Gyan Singh.
Sushil credits his 'father figure' Satpal, under whom he has trained for 13 years, as someone who has inculcated in him discipline and dedication.
Sushil created history when he became the first Indian to win a gold medal at the FILA 2010 World Wrestling Championships held in Moscow on September 12, 2010.
Sushil struggled with a series of injuries in the past year and disappointments in various international events. He finally qualified for the London Games when he outclassed 2008 Beijing Olympic bronze medallist Tushishvili Otar 3-0 on his way to a gold medal at the World qualifying tournament in Taiyuan (China) in April 2012.
