Mercedes have taken "suitable disciplinary measures" against Nico Rosberg after the German admitted his responsibility for the controversial collision between himself and Lewis Hamilton in Sunday's Belgian Grand Prix.
Hamilton's race at Spa was wrecked in the second lap when he suffered a puncture to his left rear tyre after a collision with teammate Rosberg's right-wing endplate.
Hamilton was apoplectic and claimed Rosberg admitted in a team meeting afterwards that he had deliberately caused the incident. The Formula One championship leader has, for the first time, apologised.
Hamilton was apoplectic after Rosberg hit him at Spa
Mercedes said in a statement: "Nico acknowledged his responsibility for the contact that occurred on lap two of the Belgian Grand Prix and apologised for this error of judgement.
"Suitable disciplinary measures have been taken for the incident."
Hamilton, 11 points behind Rosberg before the start of the race, is now 29 adrift after he was forced to retire late on while his championship rival finished second behind Red Bull's Daniel Ricciardo.
Rosberg, who was roundly booed while on the podium, had been on pole but Hamilton took the lead in a flying start before the first corner.
It was on the next lap that there was contact between the pair for the first time this season, which threatened all out war at Mercedes, who had been previously happy to let their drivers battle it out for the championship.
Rosberg was blamed for the crash by Mercedes chiefs
The statement added: "Mercedes-Benz remains committed to hard, fair racing because this is the right way to win world championships. It is good for the team, for the fans and for Formula One.
"Lewis and Nico understand and accept the team's number one rule: there must be no contact between the team's cars on track.
"It has been made clear that another such incident will not be tolerated. But Nico and Lewis are our drivers and we believe in them.
Hamilton had to withdraw from the Belgian Grand Prix
"They remain free to race for the 2014 FIA Formula One World Championship."
With seven races in the season remaining, it promises to be a fascinating ending to what has already been a dramatic year.
Hamilton has already indicated he will not seek retribution on Rosberg, who was blamed for causing the collision by Wolff and non-executive chairman Niki Lauda immediately after the race.
Hamilton was agitated even further following a heated team meeting on Sunday after Rosberg apparently revealed he had purposely hit Hamilton "to prove a point".
Rosberg admitted his regret but had still refused to apologise up until Friday, although having done so now will draw a line in the sand for Mercedes.
