The 5-foot-9, 193-pound safety is expected to join the eight-man practice squad for the Eagles.

"He felt bad Saturday (when he was released)," said Fraser, who coached Robinson during his all-state days at Bay City Central. "He was hurt and embarrassed and little down in the dumps. All of a sudden, he's got new life. He's excited again."

Philadelphia's current 53-man roster features five safeties in Nate Allen, Colt Anderson, Patrick Chung, Kurt Coleman and Earl Wolf. Allen and Coleman were starters for the Eagles last season while Anderson was the team's MVP of special teams. Chung was signed as a free agent from New England this offseason and Wolf was drafted in the fifth round.
