Louis Morison was an Exeter City scholar/trainee and professional between 2018 and 2021. He made one EFL Trophy appearance before joining Tiverton Town. 

Attending school in Ottery St Mary, Louis had been a member of City's academy since the age of nine before becoming a scholar/trainee on leaving school. He scored at Ipswich Town in the FA Youth Cup 2nd Round in November 2019 and, in June 2020, agreed professional terms on a one-year deal. He made his first team debut in the EFL Trophy as a substitute against Forest Green Rovers on 8 September 2020. It proved to be his only first-team appearance before his release in May 2021.

Louis had played nine times for Tiverton Town on loan during 2020/21 and Ladysmead became his destination on departing City. He was a regular for Tivvy during 2021/22 and continued in a similar vein in 2022/23 before renewing his contract for another season.

Having scored more than thirty times in just over a hundred games, Louis left Tiverton Town for Exmouth Town in October 2023.
