There's only one Ulster player in Andy Farrell's matchday squad this week with Rob Herring amongst the replacements again but here's a story for you of one Ulsterman who won his first cap in this 80s - and he was a hooker too.

John Birch was part of the Ireland team that toured Argentina back in 1970 - a time when the Irish Rugby Football Union did not recognise games against the Pumas as official Tests.

But last year, they retrospectively awarded caps to players from that tour - and Jonathan Bradley caught up with John Birch, who is now 82.

Vice-captain Pablo Matera returns to the back row after suspension as he takes over from Santiago Grondona, who drops to the replacements.
