Mathias Kiwanuka, who played nine years at linebacker and defensive end and won two Super Bowls as a member of the New York Giants, was released Tuesday by the team in an expected salary-cap move. The team officially listed the move as "failed physical" among the league's transactions, as Kiwanuka is still recovering from knee surgery. Kiwanuka was scheduled to earn $4.825 million in salary and bonuses this year and count $7.45 million against the salary cap.
