Source: Ninkovich 2-year extension

New England Patriots linebacker Rob Ninkovich recently inked a two-year extension through the 2013 season, a league source told ESPN Boston. Terms were not available.

Ninkovich was in the last year of his contract. Since joining the Patriots on Aug. 2, 2009, his role has increased each year.

A starter at linebacker in the 4-3 defense, the 27-year-old Ninkovich has also been utilized as a sub rusher this year at defensive end.
