The 43-year-old Linee discovered this year that he had the debilitating disease that affects muscle function and is often fatal.
Former Springbok captain and one-time try-scoring record holder Joost van der Westhuizen was diagnosed with motor neuron disease in 2011.
The 1995 Rugby World Cup-winning scrumhalf now spends much of his time in a wheelchair.
Linee attended the Stormers' win over the Reds at Newlands on Saturday and was on the pitch at half-time to acknowledge the crowd.
The former centre played nine tour games for the Springboks between 1993 and 1994 but was never capped in a Test.
