Force India's chief operating officer Otmar Szafnauer has said the team have been left with no option but to impose team orders between Sergio Perez and Esteban Ocon.
The duo have been scrapping with each other on track all season long and made contact on another two occasions at the Belgian Grand Prix despite several warnings to behave themselves.
Perez squeezed out Ocon twice at Eau Rouge, forcing the Frenchman to lose part of his front wing and Perez to pick up a puncture.
The Mexican eventually had to retire, while Ocon recovered to P9 but Szafnauer has stepped in to say enough is enough.
"In the future they'll never have that opportunity again," Szafnauer said on Sky F1.
"We let them race up to now, if they can't do it in a manner which is good for the team, then they won't be racing anymore.
"They shouldn't be coming together. We've given them the latitude to race. Once it gets to the point of safety margins and crashing into each other, we've got to take into our hands."
