The 39-year-old fractured his leg while playing a Celebrity Cricket League match in Dubai last month and since then he has been walking with support.
"Today (Sunday), walked without crutches for the first time since February 23. Feels as if learning to walk again in life. Still miles to go, but journey is on," Sonu tweeted.
While on the crutches, the actor finished dubbing for "Shootout At Wadala".
