One of the biggest storylines surrounding the Jacksonville Jaguars in Week 4 is how their secondary will fare against the San Francisco 49ers offense.
The Niners are dealing with several injuries ahead of the game, and a few of them are at wide receiver. Head coach Kyle Shanahan just said that Brandon Aiyuk is still recovering from the ACL injury he sustained last year, so it will be a while before he can return. Similarly, wide receiver Juan Jennings is dealing with a shoulder injury and is day-to-day.
On the other hand, San Francisco got a huge Ricky Pearsall update ahead of the Week 4 bout.
