John Inverdale is at Murrayfield as Scotland and Ireland attempt to salvage their Six Nations campaigns.

Both nations suffered home defeats in the last round of matches and Scotland still await their first win of this year's championship. However, the hosts can take confidence from their absorbing 23-20 victory in Ireland last year, when Dan Parks kicked the decisive penalty two minutes from the end.

While Scotland seek the results to match their fire and passion, Ireland have laboured since the previous Six Nations campaign. Having narrowly beaten Italy and lost to France so far, they need talisman Brian O'Driscoll to return to the form that has left him on the cusp of equalling the Championship try-scoring record.

Andrew Cotter and Phillip Matthews provide the commentary.
