The defender joined the Greens for the 2020/21 campaign from the Grecians’ Girls Development Centre and made four appearances in green before returning to Exeter.
Over the last three seasons, Grigg featured 61 times for Exeter's first and reserve teams and now returns to Home Park to help Argyle’s ongoing FA Women’s National League Southern Premier Division season.
