Ousmane Dembélé and Dani Olmo were both injured during the first half of a Champions League group-stage match in Moscow. Dembélé, the Ballon d’Or holder and Paris Saint-Germain forward, was substituted because of an injury. The game was the third round of the group stage and pitted Paris Saint-Germain against Barcelona. Olmo, a Barcelona midfielder, also left the field before halftime. The RIA Novosti report, dated October 20, did not disclose a diagnosis for either player. It also gave no estimate of how long either athlete might be sidelined. Until those details emerge, the focus will be on medical updates and the effect of the absences on each club’s next fixtures.
