Former Socceroos goalkeeper Mark Bosnich has pleaded guilty to a reckless driving charge after he knocked a cyclist to the ground with his car in the Sydney CBD last year.

The 43-year-old, who now works as a sports presenter, was charged over an incident last May in Erskine Street.

According to court documents, before the incident the cyclist had broken off the side mirror of Bosnich's car as he rode past.

After being struck by Bosnich, the cyclist was treated at St Vincent's Hospital for injuries to his ribs and left elbow.

According to police, the incident began when the cyclist moved into the middle lane, prompting Bosnich to wind down his window and tell him, "champion, you gotta pull a little to the left, you can't keep in the middle of the road".

After his mirror was knocked off, Bosnich "turned his steering wheel into the direction of the victim and moved forward, causing the front grill and bumper of the vehicle to collide into the rear of the victim's bicycle wheel".

Bosnich agreed to plead guilty to the charge when references to driving in a manner dangerous to the public were removed.

He made no comment outside court and will face sentencing in June.
