Adrian Morley is Great Britain's latest doubt for the one-off Test with Australia in July.

The former Leeds forward suffered a back injury playing for the Sydney Roosters.

He has been initially ruled out for between four and five weeks, jeopardising his availability for the game in Sydney on 12 July.

Britain have already lost scrum-half Sean Long to a wrist injury and hooker Keiron Cunningham with a broken hand.

Forced out

And prop Paul Anderson is battling to overcome a broken arm.

Morley has endured a long run of bad luck with injuries that has hampered his international career.

The second rower missed all three matches against the Kangaroos last November after failing to recover from a broken arm.

Injury also forced him out of the 1997 Super League Test series against Australia.

And he was sidelined for most of the last World Cup as well.
