The highly-rated second-rower had scored the winning try against Wigan on his return from a serious knee injury seven days earlier.
But he appeared to aggravate the problem last night and was withdrawn early in the second half in what Warrington described as a “precautionary measure”.
The 23-year-old had shown glimpses of his undoubted ability during an opening period which saw Widnes establish a 6-4 lead.
Both sides had already been condemned to bottom-four finishes at the end of the regular season and a subsequent fight with relegation in the Qualifiers.
Warrington were supposed to challenge for the Super League title this year after signing England playmaker Kevin Brown from Widnes during the winter.
Brown has underwhelmed this season but a try from the stand-off on the hour mark set the Wolves on their way to an eighth straight win over their Cheshire rivals.
Scotland international Matty Russell put Warrington ahead early on when he collected Brown’s pass and touched down in the corner.
Joe Mellor hit back for Widnes with a converted try but Peta Hiku caught a crossfield kick from Declan Patton to score in clinical fashion.
Brown then grounded another clever kick from half-back partner Patton before Russell’s second try finished Widnes off.
Leigh Centurions forward Jamie Acton will miss the rest of the season after having his ban extended to four months.
