Brown out after concussion setback

England full-back Mike Brown has been ruled out of Sunday's Six Nations match in Ireland after suffering a setback in his recovery from concussion.


Brown suffered the injury in a clash of heads during the win over Italy.


England head coach Stuart Lancaster said the squad's medical staff will continue to work with Brown to "get him back to full health".


Alex Goode is set to start in Brown's place as England target three straight wins in this year's tournament.
