The Dolphins announced Friday morning that Foster was one of five players who will begin workouts on the physically unable to perform list.
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.
Here are other injuries we are monitoring Friday:
The Cowboys also announced running back Lance Dunbar, defensive lineman Maliek Collins, defensive end Benson Mayowa and tight end James Hanna will be placed on the PUP list. In addition, the Cowboys placed running back Darren McFadden, linebacker Jaylon Smith and linebacker Damien Wilson on the non-football injury list.
- The Buffalo Bills placed wide receiver Marcus Easley, defensive end Shaq Lawson, wide receiver Sammy Watkins and defensive tackle Kyle Williams on the PUP list. The Bills also moved linebacker Manny Lawson and wide receiver Kolby Listenbee to the non-football injury list. The team placed defensive tackle Marcell Dareus, defensive back Jonathan Dowling, offensive tackle Seantrel Henderson and running back Karlos Williams on the non-football illness list, too.
Regarding Lawson, general manager Doug Whaley told reporters the linebacker suffered an "upper body injury" while working out prior to camp. The GM said there's no timetable for Lawson to return at the moment.
- Minnesota Vikings wide receiver Cordarrelle Patterson left practice early with an apparent left arm injury. Coach Mike Zimmer quelled concerns about the wideout's health after practice: "He made a great catch and it wasn't his left hand or wrist, I can tell you that. I don't think it's anything concerning, but they're taking a look at it."
