Hall, 21, made his first team debut in 2007, scoring a hat-trick and 11 goals against Hunslet.
The Vikings have been able to bring him to the Stobart Stadium with help from two local businesses, The Industrial Workers Unit and Myler’s Estate Agents.
Mike Denning from the Industrial Workers Unit said: “As a local business we work with many Widnes fans and this is one way of giving something back to the town as well as backing Paul Cullen in his quest to bring the Northern Rail Cup to Widnes.
Paul Myler, a former Widnes player added, “I’ve seen Craig play and feel he’ll be a great addition to the squad and I’m looking forward to seeing him in a Vikings’ shirt. As a local business we are happy to be supporting our local team as they aim for the Northern Rail Cup.”
Widnes boss Paul Cullen yesterday blasted his squad, which have struggled to find any form this season, having lost four of their last five games.
He said: “I am here to fix the problems behind the scenes which are obviously translated on to the field with the performances of the first team.
“There is a long term fight at this club to get it back on track. It tries to be something that it can’t afford and can’t sustain and part of my remit here is to get it on track.
“What I have found here is that there is an attempt to exist as a full time professional club and it is all peripheral, all show and does not really add up to much.”
