reunited him with former boss Micky Adams, and made his début in a 1–0 loss to Leicester City a few days later. He played regularly for the remainder of the season but with the club in decline he was unable to help to stop the Blades slipping to relegation. Regaining his place in the starting eleven at the outset of the following season, Doyle was awarded with the captain's armband as he played regularly in the centre of midfield. As the team challenged for promotion, Doyle scored his first goal for the Blades in January 2012, scoring against Yeovil Town at Bramall Lane. United failed to gain promotion, but in September 2012, Doyle signed a new three-year contract with the club, committing his future until 2015. Doyle remained a regular in the side throughout the season as United fought another fruitless promotion battle. Portsmouth On 6 July 2015, Doyle joined Portsmouth after being released by Sheffield United. Doyle was made club captain, and was an integral part of a side which finished the season in sixth place, earning a place in the play-offs; Doyle and Portsmouth ultimately lost to Plymouth in the semi-finals. He finished the season with 50 appearances and 2 goals in all competitions. He signed a one-year contract extension on 5 January 2016, keeping him at Portsmouth until the summer of 2017. Doyle retained the captaincy during the 2016/17 season; a campaign which saw Portsmouth win the League Two championship after four years in the English professional game's basement division. Though Doyle's defensive midfield partner changed several times over the course of the season, with Danny Rose and Amine Linganzi vying for a place in the first XI, Doyle remained first-choice for the screening role in front of the defence. He featured 96 times for the Blues, finding the net on three occasions. Return to Coventry City On 11 May 2017, Doyle returned to Coventry City after having captained Portsmouth to its League Two victory. He commented that he would have resigned for Portsmouth if the club would have made an offer of a contract extension. Manager Mark Robins said that he was delighted in welcoming him back to his former club. He also added that his "leadership qualities on and off the pitch can not be underestimated". In the same season, Doyle captained Coventry City to League 1 promotion, when the team won the 2017-18 League
