Mumbai, Jan 25 (IANS): Shah Rukh Khan's injury is said to be not as minor as was earlier reported. The superstar has suffered a shoulder fracture, his left knee's patellar tendon is torn and doctors have advised him complete rest.

The 48-year-old suffered the injury while shooting Farah Khan's "Happy New Year" here Thursday. He was taken to a city hospital, where he was given immediate medical aid and then returned to the set.

However, a source in the know-how of the events that ensued, told IANS that Shah Rukh went back to the hospital for more tests Thursday night.

"Shah Rukh went through fresh set of tests last night post the shoot for the injuries he incurred on the sets while shooting yesterday. His right shoulder is fractured and left knee patella is torn. Doctors have advised him to take complete rest for the next two-three weeks," the source said on condition of anonymity.

Post his injury, which is said to have been caused by a heavy door, the actor was taken to the Dr. Balabhai Nanavati Hospital.

"Happy New Year" director and Shah Rukh's good friend Farah said Thursday that the star of her film was "stubborn" about resuming the shoot, and that the "returning hero" even received a standing ovation on the sets for his bravado.

Injuries are not new to Shah Rukh.

While working in films, he had first suffered a hairline fracture on his knee cap while shooting for "Koyla" in the 1990s. In the past decade, he tore a shoulder muscle, suffered a back injury and has undergone surgery too.

In 2011, his meniscus (cartilage) in his leg got ruptured when it got stuck in a puddle.

Shah Rukh had even injured himself during "Ra.One". Just last year, he underwent a shoulder surgery to alleviate the pain which he endured throughout the shooting of the action-packed "Chennai Express".
