Fox has previously had spells on loan with National League North side Tamworth and The Heed`s league rivals Solihull Moors, but has also represented the Brewers at first-team level, scoring the winner in a 2-1 EFL Cup victory over Cardiff City back in August.
He played five times this season for Solihull and will be a welcome addition to the Heed`s currently thin midfield resources, following the departure of Luke Hannant.
Following the completion of his loan move which came hot on the heels of him signing a contract extension with Burton until 2020, Fox told the club`s official website: “I`m absolutely delighted. To go and make the step-up to the National League and hopefully get as much game-time as I can to be ready for next season”.
