The 49ers cut Pettis (calf) from their practice squad with an injury settlement Thursday, Aaron Wilson of KPRC 2 Houston reports.
Pettis spent training camp with Buffalo but didn't make the 53-man roster. He joined San Francisco as part of the practice squad in late September and then suffered a calf injury. Now that he's reached an injury settlement with the club, Pettis will be free to seek work elsewhere once healthy.
