LIVE: Axed coach's key role revealed in Roosters shift

The Roosters have kicked off to Penrith with the second half underway.

The Roosters finally get one!

Sam Walker put in a deft grubber close to the line with Sitili Tupouniua getting to the ball before Sunia Turuva and getting it down.

Sam Walker converts and it's 14-6. 

Dylan Edwards is on a roll with the goalkicking boots.

He's just converted a penalty to put the Panthers up 14-0. 

Liam Martin's got all the pain medication he needs and now he's on the bench ready to go.

Joey Manu was over!

But then the Bunker got involved.

And it's because Jared Waerea-Hargreaves impeded Dylan Edwards at the back.

Edwards was nowhere near the ball but.

"Wow, just wow," Phil Gould said on Nine's coverage. 

Nine's sideline reporter Danika Mason has described Penrith's medical team as "manic" after Liam Martin left the field.

The second-rower has potentially suffered an AC joint problem and could hardly move his arm. 

The Panthers are in again!

Dylan Edwards does it all himself. He manouvered his way around the Roosters defence then put a grubber in and scored himself.

"That is brilliant," Phil Gould said on Nine's coverage.

Edwards converts and it's 12-0. 

Liam Martin has officially left the field with his shoulder problem.

Matt Eisenhuth is on for him.

Martin fell heavily in a tackle and landed right on the point of his shoulder.
