WEST Coast will offer further support to provisionally suspended forward Willie Rioli after he released a since-deleted video declaring he's "never needed to cheat".

Rioli is still waiting to discover his fate from multiple ASADA investigations last year, the first of them where he allegedly tampered with his urine sample during a routine drug test.

The 2018 premiership player also returned a positive sample in September for a metabolite of cannabis, just a fortnight after news broke of the tampering allegation.

Rioli faces a maximum four-year ban, with the two alleged indiscretions to be dealt with concurrently. He last played in the Eagles' elimination final victory last season.

Rioli's video and an accompanying caption were posted on his personal Instagram account on Monday.

"Call it how you want!" Rioli wrote below the video.

"I'm not complaining or hiding away from my mistake! We aren't done yet I'm coming for Yous (sic) #doubters Iv (sic) never needed to cheat check my family footy resume!"

We need to get in touch somehow and see how he's going mentally, as well as physically

The Eagles would not confirm whether they had spoken to Rioli yet and are not making any further comment beyond what Adam Simpson said in his weekly appearance on Channel Seven. 

Rioli trained briefly with West Coast in January but has been in Darwin and the Tiwi Islands since February.

"We actually haven't had a chance to get in contact, so I understand the frustrations, but we've got to keep everything in check," Simpson said. 

"It's been 11 months since his suspension took place, so he looks like he's frustrated, but probably no need for that (social media post).

"We need to get in touch somehow and see how he's going mentally, as well as physically."

It's believed the AFLPA's Indigenous relations manager, Jamie Bennell, will also reach out to Willie Rioli.

His relatives Maurice Rioli, Cyril 'Junior Boy' Rioli and Michael Long are VFL/AFL premiership players and Norm Smith medallists, while another, Daniel Rioli, played in Richmond's 2017 and 2019 flags.
