England hooker Jamie George has found himself in the middle of a head injury storm after being cleared to return to the field despite showing sings of concussion.
George had been yellow carded during Saracens' Champions Cup defeat at Edinburgh for a high tackle on Luke Crosbie which resulted in a head-on-head collison.
The Saracens medical team deemed the 32-year-old fit to return to play following his 10 minutes in the sin bin but he was subsequently stood down by the match doctor.
