Casey Affleck was pictured sporting a mystery cast on his left ankle and wrist as he went for a walk in LA on Tuesday.   

The actor, 45, looked a little pained as he took in some exercise and was no doubt in a little pain. 

It’s not known how he got the injury but MailOnline has contacted a spokesperson for Casey for more information.

He sported a blue T-shirt and covered his dark hair with a navy baseball cap with ‘NY’ written on the front.

Father-of-two Casey added a multi-coloured snood to his ensemble and carried a protective mask in one hand.  

Last month, Casey denied that he was in disguise at his brother Ben Affleck’s house, dressed as a landscaper, tossing a cardboard figure of Ben’s ex Ana de Armas in the trash.

This comes after the 48-year-old actor’s split with the Cuban actress, 32, who reportedly ended things with him on the phone.

Casey told ET correspondent Rachel Smith: ‘No, that’s not me. A bunch of people sent that picture to me and I was gonna tweet some, like, joke, response or something.

‘And then I couldn’t think of one and a joke didn’t seem appropriate. And I don’t have Twitter so that wasn’t going to work. But it definitely wasn’t me.’

He said he couldn’t even confirm the breakup of the celeb couple, adding: ‘I can’t even really say if they have totally broken up for good or whatever. I would leave that to them to speak to.’ 

The Massachusetts native pointed to strain on ‘people in relationships’ brought about by the coronavirus lockdown implemented last March amid the spread of the pandemic.

He said: ‘The reality is, I think that this year has been really hard on people in relationships. 

‘I wouldn’t know because I’ve been single, but I bet there are a lot of people that have, you know, it’s been challenging to relationships.’ 

Casey is father to sons 16-year-old Indiana and 13-year-old Atticus, with ex Summer Phoenix, 42.  

Ex: Ben, 48, recently split with actress Ana De Armas, 32, who reportedly ended things with him on the phone but Casey said he's not sure they are properly over
