Yeah he has that kink in his arms while bowling.
I won't be surprised if he is a chucker. He has that dodgy action but he goes under the radar all the time.
Usman's action has been cleared , period. That should be the end of discussion. Constantly dragging Usman Tariq into this is a disservice to him. Let umpires do their job if they feel otherwise. But as far as I'm concerned, he has been cleared and that should be it.
