Absolutely not. It wouldn't make sense for him to have it before the fight. The Rinnegan gives nearly perfect control over the Juubi and the Sage could of easily dealt with the Juubi a different way; example, he could of used Yin-Yang Release during the fight to split the Juubi and the nine beasts would been born much earlier, rather than near his death. We've known for quite some time that Bijuu influence their hosts; Naruto gained the Whiskers from Kurama's influence in the womb, Roshi gained Lava Release from being Son Goku's Jinchuriki etc.
It is completely obvious what kind of influence the Juubi had on the sage. His eye was projected onto the Sage through the influence in his body, and it manifested into the Rinnegan (Sage's body suppressed the hatred therefore nullifying the Tomoes and gave birth to the Rinnegan). The Juubi is the progenitor and chakra and the earth; Sage preaches about Ninjutsu... See where I'm going here?
