Beijing Guoan suffered an unexpected blow on May 4, 2021 in the 3rd round of China's Super League. Before the half of the first half, the core of the midfield Bieira was injured in the confrontation and was forced to leave the field. After the match, senior sports reporter Wang Yi disclosed that Bieira's injury was far more than expected, which undoubtedly cast a shadow over Guoan's subsequent matches.
In this matchup, both teams walked onto the field with two consecutive losses. In the 32nd minute of the match, Vieira fell to the ground in a fight with Dalian Ren player Wu Wei, and after emergency treatment of the injury, he still persisted. However, in the 39th minute, Bieira's injury worsened and he had to be replaced by teammate Li Ke. Immediately afterward, Bieira hobbled onto an ambulance with the help of the team's staff and headed straight to the hospital.
