The British and Irish Lions have suffered a setback ahead of Saturday’s pre-tour clash with Japan after Hamish Watson was ruled out by concussion.

Watson sustained a head injury during training at the squad’s camp in Jersey on Tuesday and must now begin return to play protocols, preventing him from making his Lions debut at Murrayfield.
