total of six-months until the January transfer window. He made his debut for the club in the first round of the League Cup against Chesterfield, starting the match and playing 112 minutes before being substituted, as the club won 2–1 after extra time. After making his debut for Tranmere Rovers, Palmer quickly established himself in the starting eleven, playing in a midfield position. In a match against Shrewsbury Town on 25 August 2012, he played a role, setting up an equalising goal, as the club drew 1–1. Palmer then set up the only goal of the game, winning 1–0 against Bury on 1 January 2013. Shortly after, he signed a contract extension with his parent club, keeping him until 2015 and around the same time signed a loan extension with Tranmere Rovers until the end of the 2012–13 season. Since making his debut for the club, Palmer started every match until 15 February 2012 when Tranmere lost 2–0 against Shrewsbury Town - he was sent–off in the 6th minute for a challenge on Joe Jacobson, and served a three match suspension. After serving the suspension, he returned to the first team against Yeovil Town on 2 March 2013, coming on as a 64th-minute substitute, in a 1–0 loss. Palmer regained his first team place for the rest of the 2012–13 season. At the end of the 2012–13 season, he had made forty–six appearances in all competitions. Ahead of the 2013–14 season, Palmer returned to his parent club and was given the #22 shirt. He also stated that his aim was to make a first team breakthrough at Sheffield Wednesday following an impressive loan spell at Tranmere Rovers. Palmer made his first appearance of the season, starting the whole game in the right–back position, in a 2–1 loss against Queens Park Rangers in the opening game of the campaign. After the match, he said: "Reserve team football can be very useful but going out on loan means you can get first team games under your belt. Obviously from my experience, that's the best thing to do and I would advise any young player to do the same because it stands you in good stead. At first I was a bit sceptical of going out on loan and it can be daunting but you've just got to roll with the punches. That's what I did and it has paid off so far."
