Mercedes punish Rosberg over Hamilton crash

Formula One team Mercedes has disciplined Nico Rosberg for crashing into team-mate Lewis Hamilton during last weekend's Belgian Grand Prix, warning the German driver that "another such incident will not be tolerated."

The team said Rosberg has "acknowledged his responsibility for the contact" that occurred in the second lap of Sunday's race and "apologized for this error of judgment."

Mercedes says "suitable disciplinary measures have been taken" against Rosberg but that he is free to race in the championship.

Rosberg leads the drivers' standings on 220 points, with Hamilton in second place on 191.

Mercedes says the two drivers "accept the team's No. 1 rule: there must be no contact between the team's cars on track."
