Sharma, 28, and his friend, a Haryana Cricket Association official, were near a Metro station in Sector 21 when a Travera ferrying BPO employees, which was ahead of them, suddenly applied brakes at a speed breaker, police said.
The cricketer's car rammed into the BPO vehicle, critically injuring him and his associate, they said.
Sharma, who was apparently driving, suffered head injuries and was taken to a private hospital in the area. He was later shifted to another hospital in Pashim Vihar where he underwent a surgery.
He is in the ICU. The other injured is also undergoing treatment at the hospital, they said.
The accident occurred at around 4 PM and the BPO vehicle escaped after the crash, police said.
Sharma became famous for dismissing Pakistan's Misbah-ul-Haq in the last over of the final of the inaugural ICC Twenty20 World Cup in South Africa to take India to victory.
He is also a member of IPL team Chennai Super Kings and plays for Haryana in Ranji Trophy.
