Bengals get Nelson back, lose Johnson

CINCINNATI -- The Bengals' defensive backfield got a welcomed addition at practice Wednesday afternoon.

Safety Reggie Nelson, who missed all of last week with a hamstring injury, returned to action for the first time since going down at the end of Cincinnati's Week 3 win over Green Bay. Nelson contributed to arguably the biggest play of that game when he recovered a fumble from Packers running back Jonathan Franklin and ran with the ball several yards before having it pulled loose. The ball was scooped up by Bengals cornerback Terence Newman and returned 58 yards for a touchdown that proved to be the game-winner.

Officially, Nelson practiced in a limited capacity.

Along with Nelson, the Bengals missed cornerbacks Leon Hall and Dre Kirkpatrick in practices last week. Kirkpatrick actually participated in last Friday's session but along with Hall was held out of all of Wednesday's practice. Both defensive backs have hamstring injuries.

On Sunday, hours before the Bengals met the Browns at FirstEnergy Stadium in Cleveland, Hall and Nelson were out early running on the field. Both were jogging up, trying to loosen up their legs.

In addition to Hall and Kirkpatrick, defensive end Michael Johnson also was held out of practice. He has a concussion, according to the Bengals' injury report.

Johnson spoke to trainers after Sunday's loss at Cleveland and reported symptoms to them. They determined he was concussed.

Three weeks ago, in Cincinnati's Monday night win over Pittsburgh, he left the game to be evaluated for concussion-like symptoms after hitting his head at the end of a sack. He was cleared to return.

It's not yet clear how long the concussion could keep Johnson out.

Here's the rest of the Bengals' injury report:

Did not practice: CB Leon Hall (hamstring), DE Michael Johnson (concussion), CB Dre Kirkpatrick (hamstring), G Mike Pollak (knee)

Limited pactice participation: LB Vontaze Burfict (neck), S Reggie Nelson (hamstring)
