Sanchez said: "I thought two big lads came together and the referee gave the corner in our favour. When John stayed down I thought perhaps he had landed awkwardly or head-butted the ground.
"Clint is a strong player and so is John Terry. These things happened in football when two big men come together. I am sure it was not malicious. Clint is not that type of character.
"It should have been 1-0 to us but Cech pulled off a great save from Paul. He is a top-class goalkeeper.
"I have mixed feelings really. Anybody would have settled for a point before coming to Chelsea but when you come that close to knocking over their record, you think 'go on, let's take it'. It wasn't to be though and we only got a point from it."
But Fulham's Kasey Keller, who has taken over the goalkeeper's jersey from Antti Niemi, also made several super saves to ensure the Cottagers earned a point.
Sanchez added: "Antti kept us in the Premier League in the five games I was in charge last season so he deserves a lot of credit otherwise we would have been playing in the Championship.
"He himself knows he has had injuries and has not been at his peak. There is competition now throughout the team and we can make changes that improve things.
"When Kasey has come on, he has done what he is paid to do and that is keep clean sheets. The back four were excellent in front of him today."
