Nairo Quintana is back for the 2024 season after having apparently signed with Moviestar (e.g., see this market). He was suspended in 2022 from the Tour de France after testing positive (twice) for Tramadol. Note that "Tramadol is banned in competition by the UCI, it was only ‘monitored’ by the World Anti-Doping Agency (WADA). However, that is set to change on 1st January, 2024 as WADA adds the narcotic to the ‘prohibited in-competition’ list, so anyone testing positive for Tramadol at a race after that date will be subject to a multi-year suspension" (Escape Collective, 2023-10-28).

This question will only resolve yes if the disqualification or suspension is coming from the UCI; his team dropping him or similar without the above requirement is not sufficient.

This is my first attempt at a question, feedback welcome.
