Warrington coach Tony Smith has injury concerns over Stefan Ratchford and Ben Harrison ahead of next Saturday's play-off clash against St Helens.
The duo both limped off for the Wolves during their resounding 52-14 victory over Widnes on the final day of Super League's regular season.
The visitors ran in 10 tries at the Stobart Stadium, including two each for Chris Riley and Mickey Higham, but Smith was left hoping he won't be without Ratchford and Harrison for the upcoming home clash with Saints.
"There are a couple of concerns with knees and ligaments but hope they won't prove too serious," he said.
As for the match itself, the Wolves boss commented: "It was a scrappy game with plenty of errors. It wasn't the prettiest but we got the job done.
"Both teams chanced their arm and played a bit different to normal.
"Widnes were very spirited and were prepared to die on their feet rather than live on their knees.
"We had to dig deep and were a little bit ragged but are ready to step up next week."
Smith also revealed that experienced forward David Solomona - who kicked the final conversion - will be leaving at the end of the season.
The hammering means Widnes finish the campaign bottom of the table in their first season back in the top flight. Yet despite the heavy loss, Vikings coach Denis Betts refused to be too downbeat.
"I cannot fault our effort. The fans have seen effort in spades this season and have had value for money," he said.
"The scoreline was blown out in favour of an exceptional side but they are relentless.
"We saw some dumb stuff but all the players worked hard.
"We missed a couple of opportunities but if you had said in mid-season we would win six games we would have taken that.
"We have to build on this season and aim to be more consistent in future."
