49ers RB Christian McCaffrey (calf) limited in Thursday's practice

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.

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.

Texans second practice of Week 1.

I do not see Christian Kirk or Braxton Berrios.

Cam Robinson is back.

Related Players: Nico Collins, Jayden Higgins, Jaylin Noel

It's not looking great for Kirk to suit up for Week 1. We'll see how much Noel rotates into the slot, but it's probably best to keep our exposure to only Nico Collins until we see how the target share spreads out behind him. Collins is in easy WR1 consideration.
