Harry Wilson and Tim Ryan remain chances to face the Crusaders in the Queensland Reds’ quarter-final in Christchurch.
But Harry McLaughlin-Phillips is all but certain to be ruled out of Friday’s clash after a head knock suffered late in the side’s big defeat of Fijian Drua added to the side’s injury-riddled season.
Incumbent Wallabies captain Wilson failed to finish in Saturday’s 52-7 win at Suncorp Stadium after suffering a knock to the same arm he fractured earlier this season.
Wilson had scans on Sunday but was spotted at Ballymore on Monday and is yet to be ruled out of Friday’s sudden-death clash.
Winger Ryan (ankle) can also prove his fitness this week but the six-day turnaround will likely rule out back-up playmaker McLaughlin-Phillips.
In brighter news, enigmatic utility forward Seru Uru (knee) could return from injury for the clash.
The Reds, who ended a 25-year winning drought in Christchurch last season, will fly to New Zealand on Wednesday.
