Scotland and Ireland will meet in one of the biggest Guinness Six Nations matches BT Murrayfield has ever staged on Sunday.
The home side are chasing their first Triple Crown since 1990, while a win will also give them a shot at winning their first Championship title in 24 years.
Ireland are 60% of the way towards a Grand Slam and, if they beat Scotland and results go their way, they could leave Edinburgh as champions.
