Floyd is questionable to return to Friday's exhibition contest versus the Raiders due to a right knee injury, Jennifer Lee Chan of NBC Sports Bay Area reports.
Floyd was injured during the 49ers' second defensive series when his right leg was landed on by a teammate. He initially limped off the field to the medical tent before walking slowly to the locker room to be checked out. Floyd is slated to be a big part of San Francisco's pass rush after signing a two-year, $20 million contract in the offseason. He tied his career high with 10.5 sacks as a member of the Bills last year.
