Duke Johnson is wrapping a two-visit work week. The former Browns and Texans passing-down back worked out for the Panthers on Friday, per Adam Schefter of ESPN.com. Johnson visited the 49ers on Monday.

While widespread uncertainty has gripped San Francisco’s backfield, the 49ers went in another direction. Carolina, however, will be without Christian McCaffrey for weeks due to the hamstring injury the All-Pro suffered Thursday night. Johnson could seemingly have an opportunity for a 3-0 team that now lacks a proven receiving back.

The Panthers have rookie Chuba Hubbard and former Broncos contributor Royce Freeman. The former did catch 20-plus passes in his first two seasons at Oklahoma State, but the Canadian back did drop a pass at the goal line Thursday. Freeman did not factor into the Broncos’ passing game much during his three Denver seasons.

Johnson has excelled in this role, eclipsing 400 receiving yards in his first five NFL seasons. The Jaguars cut the former third-round pick from their practice squad last week, and while the veteran resided in free agency for months after his February Texans release, multiple teams have kicked the tires on him recently.

The 28-year-old back signed a Browns extension in 2018 but saw the team’s subsequent Kareem Hunt addition lead him out of Cleveland. Johnson missed five games last season but was productive for the Texans in 2019, averaging 4.9 yards per carry and totaling 820 scrimmage yards.
