Papua New Guinea's Francis Kompaon has missed out on a medal in the final of the men's T46 100m at the Paralympics.
The 26 year-old finished seventh in the final in a time of 12.28 seconds - more than a second slower than the personal best time he ran in the heats.
Making matters worse, Kompaon injured his hamstring near the finish line.
PNG Team Manager Rosemary Mawe says everyone is gutted but that's the harsh reality of sport.
"He's also devastated. The bronze medal is obviously 11.23 and in the heats he got 11.21 and he was sure he had put a lot of effort in there and thought he would have improved on his personal best he had in the events and I don't know how it all happened and yeah."
Meanwhile Tonga's Aloalo Liku finished last in the men's F44 discus final.
His best throw of 32.73 was a season best effort but he finished well adrift of American Jeremy Campbell who set a new Paralympic record with a throw of 60.05m.
