Natasha Perdue overcame a worrying spasm in her left leg to record a weightlifting total although it did not trouble her personal best in the women's 69kg B group.
The 37-year-old's leg gave way after her first failed snatch attempt at 92kg and, after securing a successful second lift at the same weight, she almost collapsed again before being helped to a nearby seat by Team GB weightlifting head coach Tamas Feher.
Perdue appeared for a third and final attempt at 95kg, still three kilos off her snatch PB, but then felt her left shoulder give way midway through.
A crucial interval period provided welcome physio treatment and the battling Swansea lifter was able to clean and jerk 113kg to bravely record a total of 205kg, despite that being five kilos off her previous best.
Perdue and her coaching staff subsequently decided to call it a day with a total in the bag and she passed on her following two attempts.
Perdue revealed afterwards that the injury had not surfaced in training or the build-up to the competition.
She undoubtedly takes mixed emotions from the experience but proudly follows in the footsteps of her late father, Terry, who competed for Great Britain in weightlifting at the Mexico 1968 and Munich 1972 Games.
It was enough to finish fourth out of six lifters in the B group, with another nine going in the A group on Wednesday afternoon.
