South Africa fly-half Handre Pollard is a doubt for Saturday's Rugby Championship Test against Argentina in Durban.
Pollard suffered a blow to the head in last weekend’s defeat to New Zealand. He passed an initial fitness test on Saturday, but two days’ later began to show signs of concussion.
Pat Lambie and Morne Steyn are on standby to play if Pollard is deemed unfit.
Springboks doctor Craig Roberts said: "Handre passed the head injury assessment during the game and immediately after, but then two days later there were signs of what we called delayed concussion.
"So we will only know later in the week, after further tests are carried out, whether he will be available for selection."
Better news for the Springboks was that the experienced trio of centre Jean de Villiers, scrum-half Fourie de Preez and flank Willem Alberts all made it through a training session unscathed on Monday as they aim to make a return to the side having not yet featured in 2015.
"Jean is a player who took a back seat a bit so that he could get some game time, and the news is good on that front as he looked good in training and should be available for selection for this week's game," Roberts said.
"It was also a good workout for Fourie du Preez. We will obviously monitor how he responds to the training, as we will with Jean, before making a final decision.
"Willem is also looking good. We've been building him up for a while now, and if gets through the training week then he will be ready to play."
Two more players back in training on Monday were centre Jan Serfontein and prop Steven Kitshoff.
