Damian Tsekenis

Club career Marconi Stallions Tsekenis began his football career at Marconi Stallions where he initially started in the club's under-18s squad. He scored on his first-team debut on 9 June 2019 in a 5–2 victory over Sydney FC Youth, and made a further five league appearances for Marconi. He also scored a goal in a 3–0 away victory in a Round of 32 cup match against South Hobart. Marconi progressed through to the Round of 16 for the first time in the club's competition history.

Central Coast Mariners Tsekenis signed for Central Coast Mariners during the 2018–19 Y-League season. During his time with Central Coast Mariners Academy, he sustained a fractured hand, necessitating a 12-week absence from play. Subsequently, he experienced an infection during his rehabilitation process and later incurred a medial collateral ligament tear, just two days into the pre-season, resulting in an additional 7-week hiatus.

Tsekenis signed his first professional contract with the Mariners in November 2021 and was promoted to the first-team squad. Tsekenis made his last appearance for the Mariners on 5 March 2022 against Brisbane Roar, making a total of three league appearances during the 2021–22 season.

Doping ban On 10 November 2023, it was publicly announced that a Sport Integrity Australia investigation had found that Tsekenis used banned substances, Ibutamoren and Enobosarm, and had also engaged in the use or attempted use of RAD140 and Ligandrol. These four substances are prohibited due to their performance-enhancing nature, with effects similar to anabolic steroids. He received a two-year and nine-month suspension, backdated to expire on 21 December 2024.

Marconi Stallions Following the expiry of his doping ban, on 16 January 2025, it was announced that Tsekenis had signed for his former club, Marconi Stallions, for the 2025 NPL NSW season. Tsekenis' father, Peter, is the head coach of the team.
