This is one fight against a big name that Silva can actually win at this stage of his career.
It would be a silly fight, but who knows?
Thing is, Fedor doesn't go out easily.... just ask Mr. Singh. And Silva doesn't seem to have his same killer instinct. He'd prob try a flurry against a hurt Fedor and then mysteriously, inexplicably, just back up and go back to circling with little to no action.
It would be sad no matter what happened.
