The 39-year-old suffered multiple fractures in a leg while playing in the Celebrity Cricket League last month.
"Finally, finished the dubbing of 'Shootout At Wadala'. Had to go on crutches, hop four floors up and then four floors down on one leg as the lift was out of order," Sonu posted on Twitter.
Directed by Sanjay Gupta, "Shootout at Wadala" has an ensemble case of John Abraham, Anil Kapoor, Kangna Ranut, Manoj Bajpayee, Tusshar Kapoor and Ronit Roy.
The movie is expected to release May 1.
