England scrum half withdrawn due to Covid

The RFU has a risk assessment which we use at the Club when a positive test is reported. for there to be close contact requires les than 1 metre and non-fleeting, i.e. greater than 3 seconds. Under normal training this is rarely achieved, however it may be if contact training has taken place. If the team wore masks when inside their hotels then that also reduces the close contact. I would imagine the assessment is based around those criteria.
