England head coach Eddie Jones is being forced to self-isolate for 10 days after his assistant Matt Proudfoot tested positive for coronavirus.
Jones is not displaying any symptoms and, if he returns a negative at the next round of testing, he will join up with the squad at St George's Park next Thursday.
"England coach Matt Proudfoot has tested positive for Covid-19 and is self-isolating," an RFU statement read.
"The test was carried out as part of England's tournament testing regime for the upcoming Guinness Six Nations. He is not displaying any symptoms.
"Head coach Eddie Jones and Simon Amor have been identified as contacts and will also isolate for a 10-day period, in accordance with Government guidelines."
England begin their Six Nations campaign on Saturday, 6 February against Scotland, with Ireland opening their campaign in Wales the following day.
Ireland take on England at the Aviva Stadium in the final round of matches on 20 March.
