JACKSONVILLE, Fla. — The Jacksonville Jaguars are baffled by their lack of sacks.

Comment on this story

The Jaguars have an NFL-low two sacks through four games and have failed to get an opposing quarterback to the ground the last three weeks. They sacked Christian Ponder twice in the season opener at Minnesota, but have been shut out since.

For a franchise with numerous on-the-field issues, this one tops the list.

Linebacker Paul Posluszny says "it's not good." He adds that sacks are "such an important number in this game. The more you get, the better your chances of winning."

The Jaguars (1-3) hope to reverse the trend Sunday against the Chicago Bears (3-1), who have allowed 13 sacks this season.
