You may be right about Silver not having fight against Infinite face-to-face, but let's just say that Silver's part of the Resistance force that fought against Eggman's plan in Sonic Forces. But for now, I will not try to disagree to your thought about Silver vs. Infinite. I also advised myself to wait patience until the game get released.

It's because that has same logic as Chaotix, Knuckles, Tails, Rouge, and many mobians that hadn't fought against Infinite in the game - only Modern Sonic, Classic Sonic (suggesting), and Avatar/Rookie did.
