49ers Receiver Brandon Aiyuk Misses Practice

SANTA CLARA, Calif. (AP) — San Francisco star receiver Brandon Aiyuk wasn’t at the start of practice despite the team saying he was cleared by doctors to participate. Aiyuk had refused to practice all training camp as he seeks a long-term extension or a possible trade, with coach Kyle Shanahan citing a back injury as the official reason for what is essentially a contract dispute. Both Shanahan and general manager John Lynch said before practice that Aiyuk had been cleared by team doctors and the expectation was that he would practice. But Aiyuk was not on the field during the portion open to reporters and could be subject to fines.
