Three weeks after suffering concussion from a head clash, former Sydney Roosters forward Adrian Morley remains sidelined with double vision and will miss Warrington's Challenge Cup quarter-final.

The 34-year-old Wolves captain has missed three matches since his team's bruising victory over St Helens last month.

While he has returned to light training, the 2002 NRL premiership-winner will not see game-time until receiving an all-clear from specialists, London's Daily Star newspaper reports.

"People's health and safety and their well-being and life after rugby league are much more important than any game of rugby league," Warrington coach Tony Smith said of Morley's absence from Saturday's clash with Wigan.

"Moz understands that. It's hard for a warrior like him because he wants to get out there and play but he's got to take care of the other side of his life as well."

Morley's vision problems are believed to be the result of bruising to the muscles which control the eyes, Smith said.

Since his most recent injury, Morley has faced questioning about retirement.

"I don't know where these rumours start but they're not true," Morley told the Daily Mirror last week.

"I've still got a bit of life left in me yet."
