O'Sullivan won't give up on star centres

Eddie O’Sullivan expects his Scottish counterpart Matt Williams will be “rubbing his hands together” at the prospect of facing an Ireland side minus star centres Brian O’Driscoll and Gordon D’Arcy.

O'Sullivan has put the hamstring-stricken duo on a 24-hour rehabilitation plan in a bid to race them back to fitness for Saturday’s RBS 6 Nations sell-out clash at Murrayfield.
