Ireland lock Iain Henderson has been ruled out of contention for the Sunday's Guinness Six Nations match against Italy after testing positive for Covid-19.
"Iain Henderson produced a positive Covid result during the routine testing of squad and management upon arrival into camp on Monday evening," the IRFU said in a statement.
"The positive result has since been confirmed. Iain is well and has left Ireland camp to complete his period of isolation at home.
"There are no other positive results within the group and the squad will continue to test across the week."
The Ulster captain missed the opening game of the championship against Wales with an ankle injury but returned to feature off the bench against France in the 30-24 round-two loss.
Tadhg Beirne, James Ryan, Kieran Treadwell and Ryan Baird are the other second rows in Andy Farrell’s squad.
Prop Tom O’Toole was yesterday ruled out after suffering a hamstring injury.
