Jonathan Jack Sealy (born 4 May 1987), commonly known as Jack Sealy (traditional Chinese: 積施利; simplified Chinese: 积施利; Jyutping: Zik1 Si1 Lei6), is a Hong Kong professional footballer currently playing for Hong Kong Premier League club Hong Kong Pegasus.
Jack Sealy is the son of former Queen's Park Rangers and Eastern player Tony Sealy. He was born in England and but later became a naturalized Hong Konger. From an early age he represented the Hong Kong Football Club and by the age of 12 was playing football in adult social leagues, the Yau Yee League, before making the step up to the Hong Kong Second Division at the age of 16.
Jack Sealy played for Hong Kong Football Club from 2007, with his father Tony Sealy as his coach. He scored an own goal in the 0–6 loss to Kitchee on 23 September 2010. He missed a scoring chance and then scored an own goal in the 2–4 defeat to Fourway Rangers on 17 December 2010.
Jack Sealy moved to South China in July 2012 to further his career. On 29 September 2012, Dhiego Martins scored in stoppage time from an inch-perfect cross from Sealy, helping the club beat rivals Kitchee 1–0. Sealy scored his first league goal for South China against Yokohama FC Hong Kong on 15 February 2014.
On 6 December 2011, Jack Sealy trained with the Hong Kong national football team for the first time, to prepare for the 2012 Guangdong-Hong Kong Cup. He claims that he and his father both have special feelings for Hong Kong football and his father is very supportive of his joining the Hong Kong national team. He is willing to apply for a Hong Kong passport to play for Hong Kong. He made his debut with Hong Kong on 28 December 2011 against Guangdong. In the match, he made a long pass from which Cheng Siu Wai scored the equalising goal. The match ended 2–2. He obtained Hong Kong passport in March 2013.
