The 49ers are projected to have the seventh-most cap space in the NFL at the beginning of the free-agent signing period on March 13.
The contract and salary-cap crunching website OverTheCap.com lists the 49ers with $60 million in cap space after the NFL Players Association reported the club rolled over $35 million in unspent cap money from 2018.
The 49ers last month informed veteran nose tackle Earl Mitchell they will not pick up the option on his contract, making him an unrestricted free agent next month. That move will create another $2.
