Worsfold said the club had a case to challenge Kerr's ban for striking Carlton's Marc Murphy, which drew 125 demerit points.
The case will go to the tribunal on Tuesday evening and Worsfold said the result would give Kerr an indication whether he was still overstepping the mark with his physical approach.
"The experts have had a look at what the case is and hopefully we can get a good result tonight," the coach said. "We wouldn't go there if we thought he was guilty.
"He needs to know what he can and can't do. We'll find out tonight and if he's not guilty then he's going fine.
"If he's guilty then he knows there's going to be a lot of players in strife for hitting him."
Kerr overcame a relentless tag from Carlton's Aaron Joseph in round 10 to have 23 possessions and a game-high nine clearances.
Worsfold said his football on the weekend was outstanding.
"Some of the goals he set up from stoppages, winning the ball and getting it out while under a full tackle were outstanding.
"As our side improves, he'll then win some of the easy possessions as well. But at the moment he is having to knuckle down and get in for the team and do the real hard grunt work."
Hard grunt work is something ruckman Cox has been accused of not doing in recent weeks, with former Hawthorn champion Dermott Brereton saying the All-Australian doesn't take enough heat for his young teammates.
Speaking in his role as a media commentator, Brereton said Cox was a wonderful player but needed to take some physical punishment.
"I'm not really sure where all of this is coming from," Worsfold said of the criticism.
"Because some of the people that are criticising him were also comparing him to Polly Farmer eight months ago, so something drastic has happened – I’m not sure what, but it's just a bit of a whim from some people to talk about that.
Worsfold said Cox hadn't been as much of a standout player in his past two matches, but added that by the standard applied to the League's other ruckmen he had played very good games.
"He's going very well," the coach said.
"Considering the last couple of seasons he's actually carried fairly nasty injuries through the season as well.
"But it is something that we'll be looking at as well, because the last two weeks he hasn't been as dominant as we know he can be. We’ll assess possible reasons why."
Important clearance player Matt Priddis was running laps an hour before West Coast training on Tuesday and is a chance to return to face Geelong on Sunday.
Worsfold said excitement machine Nick Naitanui is also ready to play AFL football, and the young ruckman would now be assessed weekly, based on form and the team's requirements.
The coach added he would have no hesitation bringing the No.2 draft pick in to face Geelong if he was ready.
