The Broncos are preparing as if they will not be facing their old starting quarterback Sunday. Russell Wilson (calf) was a limited participant in practice Wednesday for Pittsburgh, but head coach Mike Tomlin on Monday indicated the Steelers were proceeding as if Justin Fields would get his second start of the young season with Wilson still recovering. Denver head coach Sean Payton on Wednesday said the Broncos would start their prep with Fields. “You look at Fields last week and then you prepare for both,” Payton said.
