Harold Lindsay Vernon Day (12 August 1898 — 15 June 1972) was an English rugby union footballer and a first-class cricketer.

After serving in the First World War with the Royal Artillery, he played domestic rugby predominantly for Leicester Tigers from 1918 to 1929, becoming their record points scorer.

[5] Alongside playing for Leicester, he also captained Leicestershire to victory in the final of the 1924–25 County Championship against Gloucestershire,[5] in addition to representing the British Army.

[6] Considered at the time to be one of the greatest kickers of a rugby ball, he was known for his great power and accuracy, with an ability to score drop-goals from half-way.

[2] It was whilst representing the Army that he gained his first Test caps for England against Wales at Swansea in the 1920 Five Nations Championship,[2] in somewhat unusual circumstances.

[7] On the back of strong performances for Leicester, he earned his second and third Test caps in the 1922 Five Nations Championship, playing against Wales at Cardiff Arms Park (in which he scored a try) and France at Twickenham.

[8] Despite this, Day played an important part in denying the French what would have been a famous victory, by kicking one conversion and scoring two penalities.

[9] Beginning in 1922, he began an association with Hampshire, for whom he made his debut in first-class cricket for against Kent at Southampton in the 1922 County Championship,[10] a match in which he scored 56 and 91.

[1] He died suddenly on 15 June 1972 at Hadley Wood, Hertfordshire;[1][6] an obituary notice had been mistakenly published about Day some years prior to his death.
