He went to school at Nenagh CBS and played all his underage rugby with Nenagh Ormond RFC, representing Munster and Irish Youths, before moving to St. Munchin's College in Limerick, where he was a key member of the side that won the Munster Schools Rugby Senior Cup in 2002.
Ryan is a member of Shannon Rugby Football Club, who play in AIB League Division 1. He won an AIL league medal with Shannon in the 2005–06 season. Ryan moved to Shannon following a successful period at Nenagh Ormond, where he learnt his trade.
Ryan made his debut for Munster against Ospreys on 3 September 2004, during a Celtic League fixture. He made his Heineken Cup debut against Llanelli Scarlets on 16 December 2007. He played for Munster in their 2007–08 Heineken Cup semi-final against Saracens, and was on the bench for the 2008 Heineken Cup Final against Stade Toulousain, which Munster won 16–13.
Ryan was part of the Munster squad that won the 2008–09 Celtic League, and he added a second Celtic League winners medal to his collection when Munster beat arch-rivals, and newly crowned Heineken Cup champions, Leinster 19–9 in the 2011 Magners League Grand Final. Ryan started at Blindside Flanker in the final.
After the 2011 Rugby World Cup, he began to regularly partner Paul O'Connell in the Munster pack, particularly during the 2011–12 Heineken Cup, keeping Donncha O'Callaghan on the bench. It was announced on 13 March 2012 that Ryan had signed a contract extension with the IRFU, which will see him continue to play his rugby with Munster until the end of the 2013–14 season. Ryan won his one-hundredth cap for Munster in the Heineken Cup quarter-final against Ulster on 8 April 2012. He won the Munster Player of the Year award for the 2011–12 season.
Ryan has become the first-choice Second Row, alongside Paul O'Connell during the 2011–12 season, although injury to O'Connell has seen Ryan start more often with Donncha O'Callaghan. Ryan started all of Munster's 2012–13 Heineken Cup pool games, and was a crucial player in getting them through to the semi-finals.
In December 2013, Ryan signed a new three-year contract with Munster, which will see him remain with the province until at least June 2017.
Ryan returned from injury on 7 March 2015, coming off the bench against Ospreys.
He represented Ireland at Youth U18 level and at U21.
Ryan missed out on selection for the Ireland senior squad for the 2009 Six Nations Championship, and had to wait until the 2009 Summer Tests to play for Ireland again, earning caps against Canada and the USA. He was named in the squad for the 2009 November Tests, but did not earn any caps during the series.
Named in Ireland's squad for the 2010 Six Nations Championship, Ryan made his Six Nations debut against Italy on 6 February 2010 as a replacement. He made another replacement appearance against France on 13 February, but did not feature in the rest of the tournament. He missed out on selection for Ireland's 2010 Summer Tour, but was back for Ireland during the 2010 November Tests, and made appearances off the bench against South Africa Samoa.
Ryan missed out on selection for Ireland's squad for the 2011 Six Nations Championship, but was named in the training squad for the 2011 Rugby World Cup. He made his first start for Ireland in the World Cup warm-up against Scotland on 6 August 2011, as well as playing against France and England. He won selection in the final 30-man squad for the tournament in New Zealand, and made three appearances at the tournament, including a start against Russia and bench appearances against Italy and Wales. He was selected in Ireland's 24-man squad for the 2012 Six Nations Championship. He came off the bench against Wales, Italy and France, and made his first Six Nations start in the Round 4 game against Scotland, in which he was named man of the match. Ryan started in all of Ireland's tests against New Zealand in June 2012, as part the 2012 Tour of New Zealand, and the tests against South Africa and Argentina on November 2012.
