Broncos re-sign Greisen

The Denver Broncos have re-signed linebacker Nick Greisen.

Terms of the deal weren't immediately available.

The Broncos signed him to a one-year contract in 2009, but he suffered a season-ending knee injury in early August. The 30-year-old veteran was an unrestricted free agent.

Greisen has played for the New York Giants, Jacksonville Jaguars, Baltimore Ravens and Denver Broncos. He has 33 starts during his nine-year career.
