San Francisco 49ers receiver Demarcus Robinson has been suspended for three games by the NFL for violating the league's substance abuse policy, coach Kyle Shanahan said in an interview with KNBR on Wednesday.

Coach Kyle Shanahan confirmed to KNBR today free agent signee Demarcus Robinson will be suspended for the first three games of the regular season. This suspension stems from an arrest last November in which Robinson was charged with misdemeanor DUI. California Highway Patrol officers observed him driving more than 100 mph in southern California.

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."

Robinson signed a two-year, $9.5 million contract with the 49ers back in March after a two-year stint with the NFC West rival Los Angeles Rams. In his eight-year NFL career, which also included stops with the Kansas City Chiefs and Baltimore Ravens, Robinson has averaged 31 catches, 376 yards, and three touchdowns per season.

The San Francisco 49ers will be shorthanded at wide receiver to start the 2025 season. San Francisco head coach Kyle Shanahan told KNBR that Demarcus Robinson was suspended for the first three games of the upcoming campaign, although he left the door open for an appeal.

Earlier this week, the 49ers tried to trade for wide receiver John Metchie before the Philadelphia Eagles ultimately made the Houston Texans a better offer.

The 49ers have committed to Brock Purdy with a big extension. But the key to that deal is the guy standing behind him in the backfield.
