West Coast assistant coach Peter Sumich has labelled the ongoing media interest surrounding Daniel Kerr's impending punishment from the AFL club's leadership group as "ridiculous".

Kerr, who copped a three-week suspension for his head-high hit on Richmond's Matt White in round 15, fronted the club's six-man leadership group last Wednesday to discuss his latest on-field indiscretion.

But no firm decision was made on his fate.

Instead, Sumich, who was clearly frustrated at having to answer questions relating to Kerr, said the club's core values committee, which includes coach John Worsfold, would hand down a penalty.

"That's still going through the club process at the moment, that's what I've been told," Sumich said.

"The group hasn't met yet, that's our core values group, so we'll just go from there and see what happens.

"Hopefully within the next 12, 24, 36 hours it's dealt with because we just don't want to answer these questions all the time, it's just ridiculous really."

Kerr also served a three-week suspension earlier in the season for headbutting Western Bulldogs midfielder Scott West but Sumich was adamant Kerr had actually improved his on-field leadership this season despite his unflattering tribunal record.

"His leadership in the midfield has been outstanding whereas in years gone by he's probably been accused of just sitting back and relaxing and letting Cuz, Juddy, Fletch, these blokes, just handle it all," Sumich said.

"They've virtually been gone, except for Fletch, and he's stood up.

"I thought this year, in the games he's played, he's stepped up. All of them haven't been BOGs (best on ground) but just through the midfield his leadership has been outstanding."

Meanwhile, captain Darren Glass has been sent for scans to determine whether he has strained a muscle in his quad.

Glass, who received extensive treatment on his thigh at quarter time in last week's loss to Brisbane, ran out the game against Lions spearhead Jonathan Brown but struggled to hit top pace.

Sumich said Glass would miss one match, possibly two, if the scans showed any tear.

And Sumich denied suggestions ruckman Dean Cox was at risk of doing more damage to his injured foot by playing on this season.

Cox has been hampered by the injury for most of the year and again copped a knock to it on the weekend.

"I went to the medical meeting and they are saying at the moment . . . it's all fine," Sumich said. "Dean's very positive about it. He just needs a rest at the end of the year, that's it. His foot is OK. He got a bit of a kick on it ... but he's pulled up really well. He'll be fine for this week."
