Bradshaw, 27, has been waiting to take a physical with teams because he had surgery to replace a screw in his right foot in late January. He previously told ESPN Radio that the Green Bay Packers and Pittsburgh Steelers were interested in him.
Bradshaw received clearance from Dr. Robert Anderson, and is expected to be ready for any team's OTAs, according to a league source.
Despite battling foot and ankle problems, Bradshaw still had a productive 2012 season with the Giants, rushing for 1,015 yards and six touchdowns in 14 games. He has gained 4,232 yards with 32 TDs in his six-year career.
Bradshaw, who was due to make $3.75 million in base salary this season, was released by the Giants in early February. Bradshaw has said both sides left the door open for a potential reunion down the road.
