Former Springbok Pat Lambie has revealed how, during his career, he often continued playing despite having a concussion.
The 28-year-old retired from rugby earlier this year, following medical advice.
In an interview with The Times, Lambie revealed how he continued playing during last year's European Champions Cup semi-final against Munster because he didn't want to miss out on the opportunity to play in a final.
But how common is it among sportsmen and women that they will hide a concussion in order to stay on the field?
