Morrison played for DCU in the Sigerson Cup, winning the trophy in 2020.[4][5] He completed his degree and qualified as a mechanical engineer later that year, receiving an undergraduate position with Mercury Engineering in Leixlip, County Kildare.[2]
Morrison started against Tyrone and Monaghan in the 2018 National Football League, completing both games.[12][13] He also came on as a substitute against Mayo in the same competition.[14] His game-time was limited, first by concussion then by a fractured ankle sustained during a training session following the league game against Kildare (in which he did not play).[15]
Morrison started against Clare and Meath (regular fixture, not the final) in the 2019 National Football League, completing both games.[16][17] He did not feature in any further games, as Donegal won the National Football League Division 2 title.
With play resuming locally in August, Morrison sustained another injury while performing for his club at Fintra during the 2020 Donegal Senior Football Championship (Round 3 of the League Stage) and was stretchered from the field of play.[22] He later described the experience as follows: "It was August 16. When I went down, there was a pop and a sort of tear. And you just know. Usually, you get a bang and you think about getting back up. I knew I wasn't getting back up. There was just that amount of pain".[2] On his injuries, he said: "The damage that the MRI disc revealed was… there was cartilage damage, damage to the LCL… Both the LCL and ACL… were ruptured, the MCL… and lateral meniscus were both torn. I'd a fracture to my kneecap, a small tear to the bottom of the hamstring…there was a long list of things really".[2]
This list then became even longer when Morrison discovered he had tested COVID-19 positive on a September Monday night in Santry before a scheduled operation to repair his leg injury. He was asymptomatic and self-isolated in Donegal, then his operation went ahead in October, indicating he was COVID-19 negative at this time (six weeks after the positive test).[2]
Style of play
Donegal senior manager Declan Bonner described Morrison as follows in one of his newspaper columns in 2020: "I've worked with Conor since he was 16, and I don't know if I've ever come across anyone who revels in stopping opposition players more than he does".[23]
After Donegal's exit from the 2019 All-Ireland Senior Football Championship, former player Brendan Devenney noted Morrison's earlier departure from the panel as follows: "We don't have a centre half back, we don't have a full-back and we're short an out and out corner-back… Where young Conor Morrison went, I'm not sure… We hopefully will have another look at [him]. He looked like a tigerish corner-back".[24]

There was no doubt that the 24-year-old was revelling in that role as man-marking enforcer for his club… 'On the Monday morning I had a Covid test in Santry. That night, I received a text message saying it had come back positive. I'd absolutely no symptoms… I came back to Donegal right away and self isolated for the two weeks. My granddad passed away last year so his house was vacant. My operation was put back six weeks because of all of that. I finally got a cancellation then for October 23… With the athletics and cross country background, the gym and fitness work is something I've no bother getting stuck in to.
