South Africa goalkeeper Andre Arendse has had an injury scare during the team's latest training session.
The 35-year old goalkeeper, who was chosen ahead of number one Hans Vonk for Sunday's opening game against Paraguay, injured his right knee after falling awkwardly during a practice session on Tuesday with fellow goalkeepers Vonk and Calvin Marlin.
Arendse looked decidedly dejected when he was forced to sit out the rest of the training session, along with Pierre Issa - who twisted his ankle against Paraguay on Sunday - and Teboho Mokoena who had a strapping around his thigh.
If he is forced to miss Saturday's game, it will be a huge blow to Arendse who worked so had to play at this World Cup following his disappointment four years ago.
Fortunately the South Africans have more than adequate cover in the form of Vonk, who hass had an outstanding season with his Dutch club Heerenveen.
Issa, who had his bandaged ankle immersed in ice, is considered doubtful for Saturday's game against Slovenia.
However, Mokoena's situation was more a case of giving his muscles a chance to rest, according to the team's medical staff.
Although Issa tried to run at the start of the session, he was forced to abandon training.
After that he was seen walking very gingerly and now faces a race against time to return to full fitness.
He was also one of the few bright points of South Africa's poor African Nations Cup campaign in Mali earlier this year.
