Long snapper Jon Dorenbos signed a five-year contract extension with the Philadelphia Eagles on Saturday. Dorenbos would have otherwise become an unrestricted free agent after the season. "Jon has been a very good long snapper for us over the last year and a half," Eagles' General Manager Tom Heckert said. "Good, consistent long snappers are hard to find, and we wanted to shore up that position for the next several years. He has worked very well with (kicker) David Akers and (holder) Sav Rocca, and we're happy to have him back." The 27-year-old Dorenbos was signed late last season after longtime long snapper Mike Bartrum was injured. He's played 22 games with the Eagles including playoffs.
