The 49ers are extending their top wideout.  San Francisco has agreed to a three-year, 73.5-million-dollar extension with wide receiver Deebo Samuel.  The deal includes 58.1-million-dollars in guarantees.  Samuel had been seeking a lucrative deal to remain in San Francisco, and previously requested a trade from the Niners in April.  The 26-year-old has played in 38 regular season games since he was selected with the 36th overall pick in the 2019 NFL Draft by the 49ers out of South Carolina.
