County on 12 September. After the departure of Steve McNulty who joined National League club Tranmere Rovers on loan in October, Cuthbert was named temporary club captain, but was only given the role on a permanent basis after Nathan Jones replaced John Still as manager in January 2016. Cuthbert went off injured during a 1–0 defeat at home to Stevenage on 2 April, but despite his return to training prior to the penultimate match of the season against Northampton Town on 30 April, he did not add to his tally of 40 appearances during the season. Ahead of the 2016–17 season, manager Jones confirmed Cuthbert would remain club captain ahead of summer signings Alan Sheehan and Johnny Mullins. On the opening day of the season, Cuthbert was initially named on the bench, but an injury to Alan Sheehan moments before kick-off meant he was called up to the starting lineup. Luton went on to achieve a 3–0 win away to Plymouth Argyle, after which Cuthbert was praised for his performance by Jones. His performance also earned him a place in the English Football League Team of the Week. After making 50 starting appearances in league matches for Luton, Cuthbert triggered a one-year contract extension to keep him at the club until June 2018. The 2017–18 season began with Cuthbert once again a first-team regular in the centre of defence for Luton. He scored his first goal of the campaign in the club's 2–1 comeback victory at Wycombe Wanderers on 16 September 2017. His run in the first-team was curtailed due to a groin injury sustained in Luton's 7–0 home win against Cambridge United on 18 November 2017. The injury was initially expected to keep him out of action until January 2018, although he ultimately returned in March 2018. Cuthbert made 25 appearances in all competitions during the campaign, scoring twice, as Luton won promotion to League One after finishing in second place. He was released by Luton at the end of the season. Stevenage Following his departure from Luton, Cuthbert signed for League Two club Stevenage on 30 May 2018. He joined the Hertfordshire club on a two-year contract. Cuthbert made his Stevenage debut in the club's opening match of the 2018–19 season, a 2–2 draw with Tranmere Rovers at Broadhall Way. Cuthbert was named as Stevenage's Player of the Year at the club's end-of-season awards ceremony on 4 May
