The 49ers placed Samuel (hamstring) on the reserve/ COVID-19 list Wednesday, Mike Garafolo of NFL Network reports.
Samuel already was ruled out for Thursday's game against the Packers with the hamstring injury, but after fellow wide receiver Kendrick Bourne landed on the COVID-19 list Wednesday, contact tracing went into effect, and the former was deemed to be in the "high-risk" category. Brandon Aiyuk is in the same boat, meaning the 49ers may be down to two wide receivers (Trent Taylor and Richie James) in Week 9.
