Six Nations 2015: Sexton hopes to be concussion-free on return

Ireland's Jonathan Sexton says doctors were "right to give me a break for 12 weeks" as he prepares to return to action.

The Racing Metro fly-half sat out Saturday's Six Nations opener against Italy as he completed an enforced 12-week lay-off following four concussions in a year, having been out since he suffered a concussion in Ireland's win over Australia on 22 November.

Watch the Six Nations Rewind on BBC2 this Saturday between 10:00-11:00, as John Inverdale takes a look back at a fierce battle between Wales and Scotland from the 1980s and Brian O'Driscoll's famous hat-trick against the French in 2000.
