Robert De Niro seems to be recovering from a leg surgery that he had undergone after suffering a leg injury. The 77-year-old actor was in Oklahoma filming Martin Scorsese’s “Killers of the Flower Moon” earlier this year but the accident did not occur on the set.

De Niro, who has been starring in the films since 1963, was spotted wearing a mask, walking around Tribeca on Saturday. He wore a blue cap, a brown collared shirt, and cargo pants as he carried rolled paper and a notebook locked under his arms.

This is the first time since the accident that he has been seen without a leg brace. A massive scar was also observed across his knee.

PageSix revealed at the time, “De Niro injured his quadriceps muscle which will be treated medically in New York.” and the injury would not affect the production schedule of the Western true-crime thriller.

Robert De Niro also spoke to IndieWire of his injury, “I tore my quad somehow … [It was] just a simple stepping over something and I just went down. The pain was excruciating and now I have to get it fixed. But it happens, especially when you get older, you have to be prepared for unexpected things.”

He plays William Hale in David Grann’s 2017 nonfiction book Killers of the Flower Moon: The Osage Murders and the Birth of the FBI.

“I don’t move around a lot, thank God. So we’ll manage,” he had said of his sedentary character.
