I don't see why it's a 'dangerous tackle' really, I was freeze-framing through it, Day wasn't trying to hurt him, it was just a case of see guy with the ball, get guy with the ball.
He wasn't even looking at him whilst tackling him, he just wanted to bring him to ground and it all happened in a split second. there was no deliberate slinging around 180 degrees or whatever....no deliberate pinning or chicken winging of the arm, It was instantaneous.
Close wasn't even hurt, it just looked bad, that doesn't make it bad.
I think he should get off, or at least get a week reduced.
