Actor Jeremy Renner is counting down the days until he regains full use of his arms after an on-set injury.

The action man was spotted in Los Angeles on Wednesday (05Jul17) with his entire right arm wrapped up in a bandage, while he also sported a splint on his left wrist.

Jeremy told TMZ.com he had sustained the injuries while "working", revealing he will be able to take the medical wraps off in a couple of weeks.

He didn't name the film, in which he had taken a tumble on set, or go into detail about the apparent stunt-gone-wrong, but he has been busy shooting Avengers: Infinity War over the past few months, reprising his role as Clint Barton, aka Hawkeye.

Despite the injuries, Renner remained in good spirits, brushing off the incident as he remarked, "You know, work hard, play hard."

The actor recently shared a photo of his new arm accessories on Instagram, revealing he had pressed on with the production after the incident.

"Fall down seven times... stand up 8!," he captioned one image, adding the hashtags, "#fixedup #pushthrough".
