The Brackley-based squad have confirmed that World Championship leader Rosberg will face punishment for the incident. However, crucially, the drivers will be allowed to race until the end of the season.
The statement reads:
During this meeting, 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.
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.
They remain free to race for the 2014 FIA Formula One World Championship.
Rosberg leads Hamilton by 29 points following last weekend's race, in which he clipped team-mate Hamilton and forced the race-leading Brit out of contention. Rosberg went on to finish second behind Red Bull's Daniel Ricciardo.
