San Francisco 49ers DE Nick Bosa (knee) impressed with his running and explosiveness in a recent rehab video as he recovers from a torn ACL suffered in the 2020 season. ‘If you’ve listened to some of the Zoom interviews from the 49ers players who have signed over the course of the last couple weeks and free agency, Bosa has represented a lot of optimism for them,’ the NFL Network’s Ian Rapoport said Friday, April 9. ‘… It sounds like Bosa is going to be ready and expected to contribute mightily for this 49ers team.’
