A supremely talented forward, forward who can play in both the second and back rows, Henderson made his senior debut for Ulster in April 2012.
Henderson graduated from Belfast Royal Academy and was fast-tracked into the Ulster academy. A key member of Ireland's successful U20 campaign in the 2012 Junior World Cup, Henderson's performances were taken note of and earned him a development contract with Ulster for the 2012-13 season.
Since being promoted to the Ulster first-team proper Henderson in 2013, Henderson has shone for the Irish province, becoming one of the most physical and hard carrying forwards in the Pro12 league. His high level of performance for the Irish province led to him being called up to the Irish national side, making his debut in a loss to South Africa in November 2012.
His eye-catching showings improved to such an extent that in 2015 he was selected in the final 31-man squad to represent Ireland at the 2015 World Cup, where he is expected to have a considerable influence. Played all four of Ireland's games at RWC 2015 scoring a try against Canada.
Travelled on the tour to South Africa last summer playing in all three tests then appeared in two autumn internationals in Dublin, against the All Blacks and scoring a try v Australia.
In April 2017, Henderson was included in the British & Irish Lions squad for the tour to New Zealand.
In March 2018, Henderson signed a new contract with the IRFU that will see him continue to play his rugby for Ulster & Ireland up until at least June 2021.
Henderson played in four games of this season’s Grand Slam Natwest 6 Nations Championship success and has amassed 39 caps for Ireland since his debut against South Africa in November 2012. He also featured prominently in the 2014 and 2015 6 Nations Championship successes.
Henderson took his test cap tally to 44 by the end of the 2019 Six Nations.
In July 2019, he succeeded Rory Best as Ulster Rugby captain.
