However, Vinod's bronze has been put on hold after a protest over his disability classification.
The 41-year-old BSF man, whose father fought in the 1971 Indo-Pak war, produced a best throw of 19.91m to finish third behind Piotr Kosewicz (20.02m) of Poland and Velimir Sandor (19.98m) of Croatia.
Vinod's classification in F52, which is for athletes with impaired muscle power, restricted range of movement, limb deficiency or leg length difference, was done on August 22 by the organisers.
It was not clear on what grounds the classification has been challenged.
India's Chef de Mission Gursharan Singh told PTI that Vinod's medal stands for now.
"There was a protest from one country or may be more than one, we don't know as it can't be revealed, that there could be issues on the classification done on Vinod before the start of Paralympics," he said.
"Vinod's result, that is his bronze, still stands and a decision is unlikely to come today as it is very late now. It's expected tomorrow," he added.
"Results of this event are currently under review due to classification observation in competition. The Victory Ceremony has been postponed to the evening session of 30th August," read a statement from the Games organisers.
Vinod injured his legs while training after joining the BSF, falling off a cliff in Leh that left him bed-ridden for close to a decade during which he lost both his parents.
The F52 classification is for athletes with impaired muscle power, restricted range of movement, limb deficiency or leg length difference, with athletes competing in seated position.
It also applies to cervical cord injury, spinal cord injury, amputation, and functional disorder.
Both Bhavinaben Patel and Nishad Kumar had earlier won a silver each in women's singles table tennis class 4 and men's T47 high jump events respectively on Sunday.
