49ers' Mike Evans and Kaelon Black miss practice on Monday

San Francisco 49ers wide receiver Mike Evans and rookie running back Kaelon Black did not participate in Monday's practice due to injuries. Evans is dealing with a quad strain and could be sidelined from one week to several months, depending on the severity of the injury. Black is missing practice with an adductor injury, also with an uncertain timeline for recovery. The team has lost three of their top four running backs already, prompting the signing of Khalil Herbert. Fellow wide receiver De’Zhaun Stribling is day-to-day with hamstring tightness, while Mikail Kamara has been waived due to a torn ACL sustained over the weekend.
