Carlos Dunlap out with concussion

Cincinnati Bengals defensive end Carlos Dunlap is not practicing due to a concussion he suffered earlier in the week and will be out for a while, a league source said.

Dunlap agreed to a five-year extension with the Bengals earlier this month. The total value of the deal is $40 million, a league source has said. Dunlap will receive $20 million in the first two years, the source said, adding that there can be an additional $4.5 million in escalators.

The 24-year-old Dunlap has spent his first three NFL seasons with the Bengals. He has 20 sacks in his career, including six last year.
