The Broncos picked up their first win of the Qualifiers Super 8s at the fifth attempt when they got past Halifax last Sunday and know victories in their last two fixtures will earn them a place in the Million Pound Game if other results also go their way.
"This Saturday becomes our biggest game of the season," said London coach Andrew Henderson. "It's do or die in terms of our goal of promotion to Super League.
"Widnes are a strong side under Denis Betts and, though this season might not have gone their way, they are certainly capable of a performance on their day and have been very competitive in the Qualifiers.
"However, I have said before that this squad is more than capable of a Super League scalp and I'm certain we will give another good account of ourselves.
"They are hungry and determined for a result. It should be a very exciting game."
Widnes finished bottom of Super League at the end of the regular season but won three games in a row in the Qualifiers to boost their survival hopes before coming unstuck against Hull KR last Saturday.
Vikings coach Betts expects his team to bounce back from that setback and is urging his players to demonstrate the gulf in class.
"What we have to do this week is dust ourselves off, recognise it's still in our hands, shake off that little bit of anxiety and recognise that there isn't one player in their team that would make our team," he said. "And be a little bit confident that we're at home, have the ability to win this game and win this game well, and go out and prove that."
The Broncos underlined their potential by holding Catalans Dragons and Warrington to two-point wins and Betts admits they pose a dangerous threat.
"They still believe they can get into Super League. I don't think they're a million miles off it," Betts added.
"They haven't got anything to lose. They're enjoying it and they're playing in a fearless manner which gives them an opportunity to put you under pressure.
"It's about controlling the anxiety which has always been the problem for a Super League team."
