Youngs is the son of former Leicester and England scrum-half Nick Youngs, and the elder brother of current Leicester and England scrum-half Ben Youngs. Originally a centre, he changed to play at hooker after advice from then Tigers' coach Heyneke Meyer. Youngs played for Gresham's School and for England Schools, and also for Holt as a junior.
Club career
He made his Tigers debut against London Irish on Boxing Day 2006, broke his leg after five minutes and came off after thirteen. In the 2008/09 season, when he was persuaded to switch to hooker he was used by new head CoachRichard Cockerill in the Leicester "A" team as a hooker. In the 2010-2011 season he was loaned to the Leicester feeder club Nottingham R.F.C. where he was first choice hooker. Youngs started the 2013 Premiership final, alongside his brother Ben, as Leicester defeated Northampton Saints. At the start of the 2016-17 season he was announced as club captain for the Tigers, replacing lock Ed Slater after being injured for nearly half of the previous season.
International career
In 2007-08, he was a member of the England squad at Rugby sevens. On England's summer tour to South Africa in 2012, Youngs was taken as part of the main touring squad for experience. He played in the midweek games and his performances led to him being touted as a future England starting hooker. Due to an injury to England's first-choice hooker Dylan Hartley and the earlier retirement of second-choice Lee Mears, Youngs was awarded the number 2 shirt for England's first 2012 Autumn International match against Fiji, and was joined on the pitch by substitute brother Ben. The Youngs brothers became the second family to have a father and two sons play for England after Sir William Milton and his sons Jumbo and Cecil. An impressive performance meant that he retained the shirt for the second test. He was named as part of the victorious Lions squad for the 2013 British and Irish Lions tour to Australia. Youngs was named in Stuart Lancaster's31- man squad in August 2015 for the 2015 Rugby World Cup and went on to start all 4 games as hooker. He was controversially overlooked for the Six Nations by new coach Eddie Jones and then was injured for the Summer tour of Australia. He was overlooked again for the 2016 Autumn Internationals and was not chosen for Jones' 45 EPS Squad for the Six Nations with skipper Dylan Hartley as first-choice, Jamie George as second choice and Tommy Taylor as third choice.
