Midfielder Dean Furman and Ronwen Williams also missed training having picked up knocks in their 1-0 MTN8 final win for SuperSport United against Highlands Park at Orlando Stadium on Saturday night.
Amiens SC midfielder Bongani Zungu is also being assessed by Dr Ngwenya.
SA Football Association media officer Matlhomola Morake confirmed Tau and Mokotjo’s arrival.
“Because they had just arrived the coach decided they must just stay there [at the team hotel] and then we would all travel together to the airport [for Bafana’s departure to PE]‚” Morake said.
“Zungu is with the doctor‚ who is looking at him and the doctor really wants to make a decision by the end of today on whether he stays or goes.”
Tau had a sparkling performance‚ including the assist for the early opener‚ as Brugge took a 2-0 lead into the break against Real Madrid in the Champions League at the Bernabeu last Tuesday‚ the Spanish giants having to fight back for a 2-2 draw.
Among niggling injury concerns who returned to training on Tuesday were Mamelodi Sundowns winger Themba Zwane and Kaizer Chiefs centreback Mulomowandau Mathoho.
Right-back Thamsanqa Mkhize and goalkeeper Brandon Petersen had already withdrawn from the squad earlier due to injuries.
