The Australian born loose forward has been at Harlequins since 2012 but a dual agreement saw him running out for Ealing Trailfinders & Esher during that time. A stellar England U20 performer he has played 20 times in that age group and in 2016 he was selected for the England squad ahead of the 6 Nations.
Clifford received his first call up to the senior England squad by new coach Eddie Jones on 13 January 2016 for the 2016 Six Nations Championship.
He made his full debut as a replacement for Chris Robshaw during the Calcutta Cup match against Scotland on 6 February 2016.
He went on to take the field in all five matches as his side clinched the Grand Slam and then ran half the length of the Twickenham pitch to mark his first start with a try against Wales in the Old Mutual Wealth Cup.
Clifford won the man of the match award and went on to share in the 23-7 victory over Australia in the second Test in Melbourne and the 44-40 triumph in the epic finale at Sydney.
In 2019, Clifford's form with Harlequins earned him a recall to the England squad for the 2019 Six Nations.
Ahead of the 2019 Six Nations, Clifford has had 7 previous 6 Nations appearances. He has yet to score any points.
