CINCINNATI (AP) - The Bengals have signed end Wallace Gilberry to a contract extension, another move to keep their defensive line intact.

Gilberry was signed as a free agent last September and finished third on the team with 6 1/2 sacks. He also recovered three fumbles and returned one for a touchdown, becoming an integral part of Cincinnati's rotation on the line.

Gilberry played with the Chiefs from 2008-11. He could have become an unrestricted free agent on Tuesday when his previous deal expired.

Earlier this month, the Bengals used their franchise tag on end Michael Johnson, who had 11 1/2 sacks last season. Johnson will be paid more than $11 million this season if he doesn't reach a long-term deal.

The line was the strength of a defense that ranked sixth in the NFL.
