After being a regular goal scorer in the Scottish Leagues, Higdon then moved to Dutch side NEC Nijmegen where he spent one season before signing for Sheffield United.

He was originally used as a midfielder, but due to his height and physical presence, he was converted into a striker by manager Dario Gradi.

[8] On 22 February 2012, Higdon scored his first Motherwell hat-trick in a 4–3 win over Hibernian at Fir Park, which included a stunning overhead kick.

NEC technical director, Carlos Aalbers, cited his target-man qualities and his ability "to score goals at the highest level" as reasons for the signing.

[11] Higdon made his competitive debut for NEC on the opening day of the league season, in a 4–1 home loss to Groningen.

And his final goal during this run came in 2–1 home defeat to Heracles Almelo (29 March), despite Higdon opening the scoring.

[25] On 4 August 2014, Higdon returned to play in England, joining Sheffield United for an undisclosed fee on a two-year deal with the option of a third year.

Higdon netted his second goal for the Blades in a 1–0 win at Leyton Orient to send them through to the fourth round of the League Cup.

On 28 October 2014, Higdon netted a late brace in a 2–1 away victory over Milton Keynes Dons, which sent United to the last eight of the League Cup in the fifth round.
