Exeter City played five pre-season fixtures in July 2017, all away from home at teams based in Somerset and Dorset.
Grecians skipper Jordan Moore-Taylor equalised in the 58th minute and Jayden Stockley scored not long after to give City a 2–1 lead.
[49] The Grecians achieved an incredible comeback from a goal and a man down to triumph 2–1 in the replay to set a Third Round tie against Premier League side West Bromwich Albion.
The score was 1–1 at the end of 90 minutes, and the next significant event was a second sending off, this time the culprit being Rovers defender Manny Monthé, leaving both teams with ten men.
[50] City's third round tie against West Bromwich Albion started very poorly, conceding after only 75 seconds after Christy Pym failed to keep Salomón Rondón's long-distance shot out.
[4] City were placed in the Southern Group D, alongside the other two southwesternmost EFL League One and Two teams Plymouth Argyle and Yeovil Town.
[54] The Grecians' second match of the group stage took place at Plymouth's Home Park, where they lost 5–3 on penalties to the Pilgrims after a 2–2 draw.
