The 2021 Commonwealth Short Course (CSL) Swimming Championships have been hit with another setback, as Olympic champion Oscar Pistorius has been absent from training amidst unspecified health concerns.

Pistorius, who won the gold medal at London 2012 and the silver medal at Rio 2016 in the men's 400m sprint event, was scheduled to participate in the CSL this year. However, he has not shown up for any of the training sessions or practices leading up to the championships.

According to reports, Pistorius has been struggling with a knee injury that has affected his performance during recent competitions. He is said to be undergoing treatment and rehabilitation, but it remains unclear whether he will be able to compete at the CSL.

The absence of Pistorius from the CSL training camp comes at a critical time for the event, which is set to take place in Perth, Western Australia from March 15-21. The absence of such a prominent figure could affect the morale of the athletes competing at the championships.

In addition to Pistorius' absence, there have also been other controversies surrounding the competition. A group of swimmers have been reported to be unhappy with the way they were selected for the team, and tensions between the athletes and officials have reportedly escalated.

Despite these challenges, the CSL organizers remain hopeful that the event will go ahead as planned, despite the absence of one of its most high-profile competitors. They are working closely with medical professionals to ensure that all necessary measures are taken to keep the athletes safe and healthy throughout the championships.
