Eagles rookie quarterback and #2 overall draft pick Carson Wentz will miss most of the preseason after suffering a hairline rib fracture, the team announced today.

The Eagles gave up four sacks in its preseason game Thursday against Tampa Bay. Philadelphia traded up to get Wentz, though the team has claimed it doesn’t plan for him to be on the active game day roster this season—leaving backup duties to Chase Daniel. That leaves the preseason as Wentz’s only opportunity to get game experience—a preseason of which he could possibly now miss seventy-five percent.
