The visitors will be without close-season signing in Australia fullback Kurtley Beale who has been suspended for three weeks for a dangerous tackle in last weekend's league win.
Russell, who will make his Test return later this year, said he expected Ireland's Simon Zebo to make his injury comeback to replace the 92-time Wallaby.
"A big shame for us. He's started pretty well here, apart from the red card. It was just an incident. He's still learning the players and how they play," Russell said.
"We have other great players to fill in for him. Zebo is fit and ready to go. Louis Dupichot is a great full-back too, we have great depth in the squad at Racing," he added.
Fleet-footed Zebo and France centre Virimi Vakatawa's contracts at the Paris La Defense Arena are up at the end of the season.
Media in France and elsewhere claim Zebo could leave and various high-spending English clubs are interested in Vakatawa.
"Hopefully they sign on again. We play some great rugby here," Russell said.
"With these boys we're building a great team and a great backline. Hopefully we can keep them all on and keep building for the next few years."
Elsewhere this weekend, PRO14 champions Leinster host title holders Saracens in a re-run of last year's final.
Record four-time winners Toulouse welcome Ulster and there's an all-English tie on Sunday as Northampton Saints head to Exeter.
