Ben Cousins is back home, still unsure of what's wrong with him and no doubt having had a gutful of more unwanted media attention.

It also remains unclear whether the AFL Brownlow Medallist and Richmond onballer will be available for their round-one match in nine days' time, the season-opener against Carlton at the MCG.

Cousins had his second overnight stay at Epworth Hospital in less than a week as he struggles with stomach pain.

He was discharged on Tuesday morning after more tests and it will be several days before Cousins knows their results.

"It is expected that Ben will return to training in the next few days," the Tigers said in a statement.

Richmond also denied a front-page newspaper report on Tuesday that the club had warned Cousins to curb his drinking.

"In response to media speculation raised today, Richmond confirms that Ben Cousins has never been spoken to individually with regards to binge drinking," the Tigers said.

"The club is extremely proactive in educating players around what is considered responsible and appropriate behaviour.

"All players, as part of their development, are involved in regular education sessions."

Cousins, a recovering drug addict, is in his second year at Richmond after his much-publicised demise at West Coast, which included an AFL suspension.

He has only played for Richmond once in this pre-season.

Meanwhile, Cousins' authorised biography is understood to be nearing completion.

Secrecy surrounds details of the project, which has been underway for more than a year.

There will be enormous interest in the book, particularly given Cousins and his family have never commented in great detail about his fall from grace at the Eagles.

But the book's release date remains unclear.
