San Francisco 49ers wide receiver Demarcus Robinson has been suspended for the first three games of the upcoming NFL season for violating the league's substance abuse policy. The suspension is not yet official as Robinson and the 49ers work through the appeal process,

Here's who stood out on Day 17 of 49ers training camp. Keep in mind, second-year wide receiver Jacob Cowing did not practice.

San Francisco 49ers coach Kyle Shanahan said receiver Demarcus Robinson is facing a three-game suspension to start the season for violating the league’s substance abuse policy. Shanahan said Wednesday on the team's flagship radio station KNBR that Robinson has been suspended pending an appeal after he pleaded no contest

49ers wide receiver Jacob Cowing did not practice Wednesday. Coach Kyle Shanahan said on KNBR that Cowing is dealing with the same lingering hamstring injury that sidelined him early in camp. “Yes, it is [the hamstring],” Shanahan said on the radio, via David Bonilla of 49erswebzone.com. “ He felt it yesterday, so we had to hold him back today.”

Seeing as the Niners can’t out and trade for Packers’ now-cornerback Bo Melton (yes, they changed his position and it’s apparently going well), there are three names I suspect are at the top of the 49ers’ attainable wishlist:

The 49ers wisely have some key veterans, most prominently Nick Bosa, Christian McCaffrey and Trent Williams, on schedules designed to keep them fresh and out of the fray from time to time. Quarterback Brock Purdy is a leader in a more reserved, analytical way. Deommodore Lenoir is stepping up to push the secondary.

Rookie running back Corey Kiner has been waived by the San Francisco 49ers. Kiner, an undrafted free agent, has been one of the better performers for the 49ers in training camp. Unfortunately, he sustained an injury in the preseason game against the Las Vegas Raiders.
