Giles is considered day-to-day because of an upper-body injury, per Sheng Peng of San Jose Hockey Now.
Giles sustained the injury during Tuesday's 2-1 preseason shootout loss to Vegas. He had 10 goals and 24 points in 67 regular-season appearances with AHL San Jose in 2025-26. Giles will probably begin the upcoming campaign in the minors if he's healthy enough to do so.
