Once Hussey got out, the floodgates were opened, and Malinga was on a hat-trick by claiming new man Suresh Raina with the next ball.
The Kings' woes continued, as S. Badrinath needlessly edged an offering wide outside the off stump from Mitchell Johnson. Inside two overs, Chennai were 3/3.
Opener Murali Vijay, seeing the procession from the other end, tried to rectify the damage in the company of Dwayne Bravo, but the Trinidadian departed after picking up some boundaries with lofted strokes.
Ravindra Jadeja fell to another soft dismissal without bothering the scorer, reducing Chennai to 36/5 in the seventh over.
Vijay (18), who earlier got a "life" when he was dropped on 14, went back in the very next over, worsening Chennai's position.
