Browns RB Chris Jennings (shoulder probable) took reps ...

49ers are listing RB Christian McCaffrey as limited at today’s practice due to a calf issue.

Related Players: Brian Robinson, Isaac Guerendo

It feels like we should panic, but players are limited in practice all the time (right?). We'll keep an eye on things but Robinson should be in our queues to plug in as an RB2 in case CMC is sidelined.

Comeback no more: Raiders WR Amari Cooper has informed the team that he no longer has the desire to play and intends to retire, per The Insiders.

Cooper had signed at the end of camp in a hopeful reunion with the team that drafted. Now, he’s headed home from Las Vegas.

Related Players: Jakobi Meyers, Tre Tucker, Dont'e Thornton, Jack Bech, Brock Bowers

Well that was short-lived. Meyers should continue to be in WR2/3 consideration, while it's best to take a wait-and-see approach for the young receivers behind him.

Dolphins tight end Darren Waller (hip) did not participate in Thursday’s practice for the portion of the work the media watched. What does that mean?

Related Players: Julian Hill, Tanner Conner

The recently un-retired Waller hasn't seen much of the football field this summer, which makes him a complete stay-away until we get some good news on that end. If he doesn't suit up, receiving work would presumably fall to Julian Hill, though he's earned only 26 targets through his first two years in the league, so this situation is best to avoid for now.
