As a result, Chris Coleman is expected to pick the same XI that started the England match.
Victory would secure Wales' spot in the knockout phase, in their first major international tournament since 1958.
Russia's Oleg Shatov is struggling with a groin problem and is doubtful to feature in Toulouse.
With Russia having underperformed thus far, coach Leonid Slutsky may be tempted to make wholesale changes.
"Whilst everybody will look at this game as the be all and end all, whether we progress or not, it's not the end of the journey for this team," Coleman said.
"Our players have done unbelievably well. It's been an eye-opener and hard, of course. It's really intense but it's been enjoyable."
Wales fans will spend the run-up to kick-off poring over the permutations to work out exactly what result means what in Group B, and what their team need to do to qualify for the knockout stages. The simplest equation of them all is; beat Russia and they are into the last 16.
Manager Coleman will have used the last few days to repair morale after the heartbreaking last-gasp defeat to England. When asked if it was one of the lowest moments of his career as a player or manager, he said: "Yes, yes. I'd have to say yeah, to be honest, when you come that close."
The Wales boss has put barely a foot wrong over the last two years, but he has been criticised in some quarters for the tactics his side employed against England.
Accusations that they were too defensive seems harsh, given they were just seconds away from securing a famous point which would have edged them closer to what would be a historic qualification.
Russia, one way or another, have disappointed, both on and off the pitch. Coach Leonid Slutsky has said the distraction of their hooligans hitting the headlines has had absolutely no impact on his side's performance against Slovakia. But, it took them about 70 minutes before they got going in Lille and it was a case of too little, too late as they lost to two fine goals from Marek Hamsik and Vladimir Weiss.
