Cotto grappling Clottey, is it intentional? is it a foul?

[Bx730NY]

Funny thing is that it wasn't a grapple or bodyslam. Clottey lunged at Cotto to grab on and Cotto dipped and came up while trying to push Clottey back. In the process, Clottey legs went in an undesirable direction and he fell flat.

That is not Cotto's fault. Clottey lunging grab try was responsible for the whole thing so he has nobody to blame but himself. At no point did Cotto wrestle him down or ever grab him for that matter.
