 Field was promoted into the first team group during the 2016–17 pre-season and the departure of long-term left back Jake Bidwell on 1 July 2016 meant that he became the only available left back, which allowed him to play the full 90 minutes in friendlies versus Vfl Bochum and Wycombe Wanderers.Field made his first competitive appearance of the season versus Exeter City in the EFL Cup first round on 9 August 2016 and played the full 120 minutes of the extra time defeat, but he could not break into the league lineup due to the arrival of loan left back Callum Elder.After a period out with an injured groin, he made his first league appearance of the season as a second-half substitute for Yoann Barbet during a 2–1 victory over Burton Albion on 10 December.
