In 2018, teenage footballer Ben Davis became the first Singaporean to sign a professional contract with an English Premier League club, Fulham, only to have his national service deferment rejected. He then failed to report for enlistment and was declared an NS defaulter in February 2019, sparking a fierce national debate over talent versus duty.

Davis, 17, signed a two-year professional contract with newly promoted Fulham in July 2018, a landmark for Singapore football. His application for long-term NS deferment was rejected by the Ministry of Defence, which conveyed the decision on 11 June 2018. MINDEF said deferments are granted only to those who represent Singapore at top-tier international competitions like the Olympics and are assessed as potential medal winners; in the past 15 years, only three sportsmen had qualified, namely swimmers Joseph Schooling and Quah Zheng Wen and sailor Maximilian Soh.

The decision prompted public criticism that Singapore was squandering a rare chance to advance its football. An online petition calling for Davis's deferment gathered thousands of signatures. His father Harvey Davis, founder of the JSSL football academy, told Reuters the family might have to choose football over Singapore citizenship if forced, noting his son holds British, Singaporean and Thai passports. His elder son had completed NS, and Harvey said he intended all his sons to serve eventually.

Defence Minister Ng Eng Hen explained the decision in Parliament on 6 August 2018, noting that Fulham's own website listed Davis's nationality as English, not Singaporean, undermining the claim that deferment would serve Singapore's interests. MINDEF added it would be unfair to approve deferment for personal career pursuits when all male Singaporeans put aside their ambitions to serve, citing footballers like Fandi Ahmad's sons Irfan and Ikhsan Fandi who completed NS before pursuing professional careers.

On 18 February 2019, MINDEF declared Davis an NS defaulter: he had failed to report for enlistment as required and was staying overseas without a valid exit permit, offences under the Enlistment Act punishable by up to $10,000 in fines and three years' jail. The Football Association of Singapore, which had initially supported his deferment appeal, condemned his conduct as thoroughly irresponsible, saying it reneged on assurances that he would discharge his NS obligations and play for the national team.

The saga remains Singapore's most polarising sports controversy, pitting the sanctity of national service against the once-in-a-generation opportunity it cost a young footballer.

The Football Association of Singapore's spokesman called Davis's failure to report thoroughly irresponsible, saying it reneged on assurances from both Davis and his father that he would discharge his NS obligations and turn out for the national team. Davis has since built his club career abroad, but the defaulter label follows him in Singapore to this day.
