The Facts: Foster signed a one-year deal with the Miami Dolphins last week, but he won't be on the field for the start of training camp. The Dolphins announced Friday morning that Foster was one of five players who will begin workouts on the physically unable to perform list.

Diehards Line: It's interesting that Foster would start on the sidelines after the running back insisted last week he was healthy. This seems like a more of a precautionary move for Miami. After all, Foster is a soon-to-be 30-year-old back coming off an Achilles injury, with a history of soft-tissue injuries. Still, Foster must prove he's healthy enough to start the season on the field. He has a shot to see a significant amount of snaps alongside Jay Ajayi and play a key role in the passing game. Running back Damien Williams is among the other Dolphins opening camp on PUP. We'll follow up as needed.
