Disgraced former West Coast Eagles star Ben Cousins is due in court on Thursday to face a drug possession charge after being sacked by the club on Wednesday night.

Cousins was arrested in Perth's entertainment district of Northbridge on Tuesday and charged with possessing an illegal drug and refusing to take a blood test.

The former Eagles captain and 2005 Brownlow medallist is due to appear in the Perth Magistrates Court at 9am (WST).

At a press conference on Wednesday night, West Coast Chief Executive Trevor Nisbett said Cousins' contract had been terminated and there was no chance he would play for the Eagles again.

"It's tragic it's got to this stage, but it was felt it had to be made," Nisbett said.

"And we're sure we've made the right decision for Ben's health."

Teammate Daniel Chick was arrested in a separate incident, only to be released without charge.

But a passenger in the car driven by Chick was charged with possessing cocaine and cannabis and will appear in the court next Monday.

Police said questioning of Chick, 31, and his 33-year-old passenger led to raids on two homes which uncovered quantities of cocaine, cannabis, methylamphetamine and drug paraphernalia.

Seven months ago Cousins was suspended indefinitely by the Eagles, after which he entered drug rehabilitation in California.

He returned to the field in July on condition he agreed to a zero tolerance clause to testing positive to banned substances and did not fall foul of the law.

Nisbett on Wednesday said he did not know if Cousins had passed a voluntary drug test following the death of his mentor former Eagles wingman Chris Mainwaring on October 1, as previously reported.

Cousins is almost certain to be de-registered by the AFL, ruling out the prospect of him being drafted by any other club.
