SANTA CLARA, Calif. (AP) — The loud piped in noise at practice, silent counts and other preparations that usually accompany a trip to Seattle aren’t necessary this year for the San Francisco 49ers. With the Seahawks one of the teams that still isn’t allowing fans in the stadium because of the coronavirus, the Niners will only have to deal with the 11 defenders on the field for Seattle instead of the vaunted 12th man when the teams play Sunday. “It’s definitely weird,” All-Pro tight end George Kittle said.
