QPR face potential sanctions from the Football Association after Rangers fans threw objects at Chelsea players during the Blues' 1-0 win at Loftus Road on Sunday.
Plastic bottles, coins and matchday programmes were among the items hurled and Branislav Ivanovic was struck by a cigarette lighter as Chelsea celebrated Cesc Fabregas' 88th-minute winner.
The FA will wait for referee Andre Marriner's report before deciding whether to take action but QPR could be hit with a fine as punishment for failing to control their fans.
Rangers manager Chris Ramsey said: "We don't want any objects thrown on the pitch.
"We know the hostilities between fans can sometimes go too far and if that is the case we'd like to make sure that's not somebody who is encouraged to come back into the club."
Chelsea manager Jose Mourinho made light of the unsavoury incident, insisting the game was conducted in the "correct" manner on and off the pitch.
"The game was correct on the pitch and in the stands," Mourinho said.
"If at the end of the game somebody threw a pound, put the pound in your pocket and go. If it is a chocolate, eat. No problem.
"Do my players need a pound? Everyone needs a pound. Never throw a pound away."
The win saw Chelsea restore their seven-point lead at the top of the table while QPR remain in the relegation zone, two points adrift of safety.
Fabregas' strike was the Blues' only shot on target during a disappointing West London derby, which QPR could have won had Thibaut Courtois not denied Matt Phillips' close-range effort in the second half.
"Were we fortunate? Yes. It was a typical game for 0-0," Mourinho said.
