The Belgian winger was a spectator during the game at Stamford Bridge, which Chelsea won comfortably thanks to a brace from Samuel Eto'o and a late strike from Demba Ba.
After the game Chelsea boss Jose Mourinho refused to go into detail, but admitted that Hazard had been dropped because of his time keeping.
"I don't want to lie," he said. "He's not injured. He forgot the time.
"Let's end the story. He's a kid, kids make mistakes and fathers they have to be clever in the way they educate their sons.
"He didn't play, he wanted to play. He's sad because he wanted to play."
According to the Sun, Hazard was late for training because he lost his passport which delayed his return to London from France.
The paper claim that Mourinho allowed him to return to watch his former side Lille beat Monaco 2-0 on Sunday, but that he lost his passport and was unable to board his train back to London in time to make training.
The Chelsea boss insisted that the matter would be put behind them quickly, and that Hazard will be in contention to feature against West Brom tomorrow.
"On Saturday (against West Brom), he will be with the team. He's a player who is a talent. On Saturday, he will be on the bench or playing."
