The Raiders have placed RB Kenyan Drake on the non-football injury list to open training camp. The team didn't announce what injury is keeping Drake out. He was seen working on the side with trainers at Wednesday's practice, though. We'll keep an eye on his status in the coming days. RBs Jalen Richard and Theo Riddick, meanwhile, landed on the COVID list. Maybe Josh Jacobs will get a few more chances to show Vegas coaches he can catch passes.

Update: Drake returned to practice on July 30.

Lions RB Theo Riddick (knee) is not listed on the final injury report after putting in a full practice on Friday. His return is excellent timing with the departure of WR Golden Tate and his 9.9 targets per game. Riddick should step back into to a sizable role in the passing game, making him a low-end PPR option. His return also puts a dent in RB Kerryon Johnson’s target projection.

Undrafted free agent RB Zach Zenner latched on with the Lions.  Zenner hails from South Dakota St. but gained a cult following in the pre-draft process thanks to an impressive combination of production and measurables.  He posted 3 straight 2,000-yard rushing seasons with 58 TDs over that span.  He also caught 77 balls during that 3-year stretch.  Then Zenner checked into the Combine at 6'0, 223 pounds and ran a 4.60-second 40-yard dash with a 41-inch vertical and 121-inch broad.  That gave him the 2nd highest SPARQ score in this year's RB class -- behind new teammate Ameer Abdullah.  Detroit's backfield is currently a bit crowded with the 2 rookies, Joique Bell and Theo Riddick.  But Bell turns 29 in August and Riddick only looks like a pass-catcher.  Zenner is capable of emerging as a "big back" complement to Abdullah down the road.
