Olympian Jitender Kumar (56kg) and Santosh Harijan (52kg) lost in the semi-finals to settle for bronze medals in the 16th Elite Men's International Boxing Tournament in Almaty, Kazakhstan.
Jitender, making a comeback to the international arena after his bronze medal winning performance at the 2009 Asian Championship, was up against Jakipov of Tajikistan.
The 22 year old took a 2-1 lead in the opening round but the Tajik boxer came back in the second to take a two-point advantage.
He further stretched the lead in the third and eventually went on to claim the victory at 12-8.
"I am disappointed with the result but satisfied my performance in the tournament. This was my first competition after a long break and I hope to do well with more match practice," Jitender said.
Santosh, a silver-medallist at the 34th National Games in Jharkhand, went down to Ali Baybozov of Kazakhstan.
Santosh, who was leading 2-1 after the first round, lost the advantage to the Kazakh boxer with the score tied at 7-7 after the second.
In the final round, Baybozov took the vital one point lead that helped him secure the win at 10-9.
