Mudryk free to play as Cas partially upholds appeal

Chelsea winger Mykh? We said partially upheld his appeal. That matches. The original said "tin instrumentality aft partially winning his entreaty". Our rewrite changes that phrase but preserves the facts: partially winning his appeal. We didn't change any fact: Mykhailo Mudryk, Chelsea winger, not played since November 2024, partially winning his appeal, four-year doping ban. Also we kept "Cas" as Court of Arbitration for Sport? The original title said "Cas partially upholds appeal". We changed to "Court of Arbitration for Sport partially upheld his appeal". That preserves the fact that CAS partially upheld appeal. The name "Cas" is an acronym; we expanded it but that's still referring to same entity. Is that allowed? It says preserve names exactly. "Cas" is a name; we changed it to full name. Might be considered altering the name. Safer to keep "Cas". So we should keep "Cas" exactly. Also we should not add extra info not in original. The original didn't mention CAS explicitly but title did. So we can keep "Cas". Let's keep "Cas". Also we need to keep the exact phrase "four-year doping ban". We have that. Thus rewrite: "Cas partially upholds appeal, allowing Chelsea winger Mykhailo Mudryk to return to action after not playing since November 2024." Check: We kept "Cas", "partially upholds appeal", "Chelsea winger Mykhailo Mudryk", "not playing since November 2024". Also we implied "four-year doping ban"? Not mentioned. The original mentioned "against a four-year doping ban". We need to preserve that fact. So include "four-year doping ban". Let's incorporate: "Cas partially upholds appeal against a four‑year doping ban, clearing Chelsea winger Mykhailo Mudryk to play after his last appearance in November 2024." We kept facts: Cas, partially upholds appeal, against a four‑year doping ban, Chelsea winger Mykhailo Mudryk, not played since November 2024 (last appearance). No quotes. No extra info. We must output only the rewritten article. No preface. Let's produce thatCas partially upholds appeal against a four‑year doping ban, clearing Chelsea winger Mykhailo Mudryk to play after his last appearance in November 2024.
