Acton it was against Leigh

No, his was on Anthony England. Think it was the first tackle of the game.

That's him, big bald prop.
Fifita hasn't appeared 100% since that one

Fifita ran straight at Brett Ferres and I'm sure Ferres went really low and put his shoulder into Fifita's knee and instantly caused the damage. Ferres isn't small himself...not illegal in my opinion although Ferres does have a disciplinary history when it comes to tackle technique..

Noticed Leeds went sideways into lower legs quite a few times during the game.

Fifita was iced up and limping after Wigan game and although he has soldiered on he hasn't quite looked the same player. Think the lay off will do him good

Speaking to Stuart Dickens after the Leeds game and he said Fifita had complained of being cannonball tackled 4 times and chicken winged twice in the few games previous. I seem to remember Stuart's speech after the Huddersfield game contained something about Fifita being a big guy in form has made him a target to be stopped but players need to find a way to tackle him legally and referees have to think more about player welfare when the opposition are purposely trying to attack the shoulders and knees. I don't think there was anything malicious in the tackle from Ferres, just looked like an awkward collision.

Wouldn't that be a first

Ferres does seem to make a habit of nasty tackles, and now he's piled on the weight it's made it even worse. He doesn't get the benefit of the doubt with me.

I think Ferres is a grub - but I've watched that tackle several times (subscribe to Trinity TV!) and I can't see anything wrong with it; maybe just an unlucky aggravation of a previous injury?
