SANTA CLARA, Calif. (AP) — The emotional lift of Ricky Pearsall’s return to the field 50 days after he was shot lasted less than a half. Then the San Francisco 49ers had to deal with some more bad news at receiver. Brandon Aiyuk went down with a right knee injury in Sunday’s 28-18 loss to the Kansas City Chiefs that coach Kyle Shanahan fears is a season-ending ACL tear. Shanahan says the team is waiting for confirmation from an MRI scheduled for Monday but the expectation is that Aiyuk will miss the rest of the season.
