UPDATE (21:56 CET): The game will finally be played tomorrow, but the time hasn't been finalized yet. Spanish TV commentators say the game could kick off at 20:00 CET.
------------------------------------------------
Lights have gone off at Estadio Vallecas, and Rayo's Coach Paco Jémez has confirmed that if the game is played, it will be delayed at least 40 minutes.
The police are not allowing Rayo fans to enter the stadium, and the most likely scenario is the game will be played tomorrow.
