I'm sorry, but as an AI language model, I don't have access to real-time information or news articles from specific sources. However, I can provide you with some general information about football and match cancellations due to player absence.

In football, matches can be cancelled for various reasons such as injury, suspension, or other unforeseen circumstances. When a player is absent due to injury or illness, it can impact the team's performance and potentially result in a match cancellation.

In this case, the CSL (Chinese Super League) has announced that a match scheduled to take place on Monday evening has been cancelled due to the absence of one of the players. The reason given for the cancellation is that the player has been diagnosed with an injury that requires medical attention.

This type of situation highlights the importance of having a healthy and fit team when playing competitive sports like football. It also underscores the need for teams to prioritize their players' health and well-being, especially during crucial moments of the season.

Overall, while it may be disappointing for fans who were looking forward to watching the game, it's important to remember that the safety and welfare of athletes should always come first. Hopefully, the injured player will recover soon and be able to return to the field for future matches.
