BEIJING - Visiting Shanghai Port upset Beijing Guoan 2-1 here on Thursday in the 13th round of the Chinese Super League, further solidifying their leading position in the standings.

The hosts faced an early setback in the 17th minute as striker Yang Liyu was brought down by Shanghai Port's midfielder Cai Huikang. Yang's injury proved too severe for him to continue, forcing Beijing Guoan to make a substitution.

In the 39th minute, Beijing Guoan almost broke the deadlock with a header from Arijan Ademi, but a VAR review disallowed it for offside.
