first senior goal in a win against Northampton Town in September. "I ran over to the fans to celebrate, but I didn't know what to do," said Nelson. In April 2013, he became the youngest Plymouth Argyle captain since Norman Piper in August 1967 when he led the team in a win against Cheltenham Town. "It was a great honour. To be the captain at such a young age, I wasn't expecting it at all." Nelson made 32 appearances in the 2012–13 campaign and scored three goals. On 7 May 2014, Nelson committed to the Pilgrims by signing a new two-year contract with the club. Oxford United On 4 July 2016, Nelson signed for newly promoted League One club Oxford United on a two-year contract, later extended by a year. An independent transfer tribunal was required as Nelson was an academy graduate aged under 24 and the two clubs were unable to agree a fee. The tribunal ruled a fee of £200,000 was payable with an additional £80,000 depending on appearances. Before the start of his second season at the club, following the departure of John Lundstram, he was appointed team captain. He suffered a ruptured Achilles tendon during a home defeat to Northampton Town in November 2017 and was ruled out for the remainder of the season, teammate John Mousinho replacing him as captain. Nelson returned, earlier than expected, to the first team as a substitute on 14 April 2018 was immediately handed the captain's armband, though Mousinho later took the armband permanently. Nelson declined a contract renewal and left Oxford after the 2018–19 season, having appeared 121 times in all competitions, scoring 8 times, in his three seasons with the club. Cardiff City Nelson signed for newly relegated Championship club Cardiff City on 27 June 2019 on a free transfer on a two-year contract. He made his debut as a substitute in place of Marlon Pack during a 3–0 defeat to Reading. He scored his first goal for Cardiff on 2 November 2019 in a 4–2 win against Birmingham City. Nelson signed a two-year extension on his contract on 7 September 2020, keeping him in the Welsh capital till 2023. Blackpool On 28 January 2023, Nelson signed for Championship side Blackpool on a deal until the end of the season after leaving Cardiff by mutual consent.
