What happened: San Francisco will place Ricky Pearsall on season-ending injured reserve before surgery to repair his PCL. New Orleans coach Kellen Moore confirmed Bryan Bresee will undergo surgery on the torn ACL he sustained last week.

Why it matters: San Francisco must replace a projected starting receiver, while New Orleans loses a starting interior defender. The timing forces both clubs to reset their depth charts before preseason games begin.

What to watch: Watch for the corresponding injured-reserve transactions and how both teams redistribute first-team snaps during camp.
