NFL Network's Mike Garafolo's injury updates on wide receiver Brandon Aiyuk and Ricky Pearsall at the start of the San Francisco 49ers' training camp.

The San Francisco 49ers, ramping up for training camp, made a flurry of Friday moves that feature Brandon Aiyuk... Pearsall had been dealing with a hamstring injury during the team’s OTAs; there doesn't seem to be grave concern here and he can of course be activated at any point during training camp.

The 49ers placed six players on their active/physically unable to perform list Friday, including wide receivers Brandon Aiyuk (knee) and Ricky Pearsall (hamstring). And Jauan Jennings is upset over his contract and will reportedly request a trade if he cannot secure a new deal before the season.

The direction of the San Francisco 49ers franchise rides on head coach Kyle Shanahan's confidence in his team's most important player.
