The France international has not featured for Los Blancos in La Liga since November 24, but he is now available for selection, with Los Blancos head coach Carlo Ancelotti confirming the boost during his pre-match press conference before the squad was confirmed.
"Camavinga is fine. He's available for tomorrow," said Ancelotti.
Kylian Mbappe is not available, with the France international suffering a thigh issue against Atalanta BC in the Champions League.
The forward will travel to Qatar for the final of the Intercontinental Cup, though, and his participation in that match has not been ruled out, suggesting that it is only a minor issue for the 25-year-old.
Camavinga returns to Real Madrid squad against Rayo
"Kylian is not serious, he won't be here tomorrow, but he will travel to Qatar and there, we will assess the risk," said Ancelotti when questioned on the former Monaco youngster.
Dani Carvajal, Eder Militao and David Alaba are all still missing for Los Blancos, while Ferland Mendy is yet to recover from a muscular problem and will again be absent on Saturday.
Sergio Mestre, Lorenzo Aguado, Victor Munoz and Youssef Enriquez are notable inclusions in the squad, with Ancelotti calling upon several young talents from Real Madrid Castilla.
Real Madrid are currently second in the La Liga table, two points behind leaders Barcelona with a game in hand, so a victory on Saturday would, temporarily at least, move them to the top of the division.
Real Madrid squad vs. Rayo Vallecano:
Courtois, Lunin, Mestre; Vazquez, Vallejo, F Garcia, Rudiger, Youssef, Asencio, Lorenzo; Bellingham, Camavinga, Valverde, Modric, Tchouameni, Guler, Ceballos; Vinicius, Rodrygo, Endrick, Brahim, Munoz
