Before the latest accident, Carl had regularly attended court sessions during brother Oscar's murder trial in Pretoria, which is nearing its end. The judge will deliver a verdict in the trial on Sept. 11.
Oscar Pistorius, 27, faces 25 years to life in prison if convicted of premeditated murder for shooting girlfriend Reeva Steenkamp on Feb. 14, 2013. He also could be sent to prison for 15 years if convicted on a lesser murder charge or sentenced to at least five years in jail if found guilty of a negligent killing.
The world-famous disabled athlete claims he killed Steenkamp by mistake, thinking she was an intruder in his home when he shot four times through a toilet stall door in the night.
