The Steelers lost another veteran in free agency Wednesday and will investigate signing another today.
Will Allen, who started seven games in 2012 for injured Troy Polamalu, became the second backup safety to leave the team when he signed with the Dallas Cowboys. Ryan Mundy signed with the New York Giants last week.
Allen played three seasons for the Steelers, who signed him as a free agent from Tampa Bay in 2010.
Today, former Giants halfback Ahmad Bradshaw, 27, will visit the Steelers and undergo a physical.
He fought through a right foot injury that has bothered him the past two seasons to rush for 1,015 yards in 2012 with a 4.6-yard average per carry, the same as his career average.
The Giants drafted him in the seventh round from Marshall in 2007 after he ran for 1,523 yards for the Herd as a junior. He had early fumbling problems in New York, but, after he led the Giants with 1,235 yards rushing in 2010, they signed him to a four-year, $18 million contract with half guaranteed.
Bradshaw had a screw inserted in his broken right foot late in January that reportedly would require a 10-week recovery. The Giants released him Feb. 6. He had his walking boot removed last week.
