Geoff Mosher of CSN Philly reported Friday that the team has rescinded their low tender on the restricted free agent, leaving Polk free to sign with anyone.
Polk stayed away from the team's offseason program after refusing to ink their $1.54 million offer. The Philadelphia Inquirer hinted that the fourth-year runner wanted out of town after coach Chip Kelly added both DeMarco Murray and Ryan Mathews to a backfield already equipped with the versatile Darren Sproles.
Polk has seen just 57 carries in two seasons under Kelly. The 222-pound hammer was used mostly as a short-yardage specialist, but even those snaps were bound to dry up on such a crowded roster.
