Pat Lambie is set to announce his retirement from rugby due to the effects of an accumulation of concussions.

The former Springbok flyhalf spent several months recovering from a terrible knock to the head that he suffered in a collision with Ireland flank CJ Stander in a Test at Newlands in June 2016.

He then collided with Sharks teammate Rhyno Smith during the first half of a Vodacom Super Rugby clash against the Kings in May 2017, with the incident sparking a sequence of speculation that it was a concussion that could throw the future of his rugby career into jeopardy.

In September 2017, Lambie signed a four-year deal with French club Racing 92.

On 30 December last year, the 28-year-old sustained an eye socket injury during the early stages of Racing’s Top 14 clash against Oyonnax and had to be taken off the field.

Lambie played 56 Tests for the Springboks from 2010 to 2016, scoring 153 points.

In 2014, he famously kicked a late, long-range penalty against the All Blacks to give the Boks a 27-25 win.
