Harrison, Dunlap miss Bengals practice

CINCINNATI -- As the Cincinnati Bengals practiced Wednesday, a trio of defenders missed the workout with injuries picked up the past two weeks.

Linebackers James Harrison and cornerback Terence Newman, weren't surprises. Newman sprained an MCL in Week 15's win over Indianapolis and was ruled out for 1-3 weeks. He is currently in the middle of Week No. 2. Early in Sunday night's loss at Pittsburgh, Harrison suffered a concussion.

Defensive end Carlos Dunlap's absence, however, wasn't expected. Although he was a little slow to get up from the game's final play, he didn't miss any time Sunday and didn't seem to show any ill effects after the game. Officially, though, he landed on the Bengals' first injury report of the week with a concussion.

In his news conference Tuesday, coach Marvin Lewis said the Bengals were optimistic they would enter this Sunday's game against the Minnesota Vikings healthy.

"We seem to be OK," Lewis said.

Along with Harrison, Dunlap and Newman, guard Kevin Zeitler was limited Wednesday. Tight end Jermaine Gresham practiced in a full capacity after injuring his abdomen in Sunday's game.

It was the third straight practice Harrison missed, dating back to last week. Harrison was sick Thursday and Friday, thanks to a bug that spread across the team. Vontaze Burfict and running back BenJarvus Green-Ellis also had the illness.

Punter Kevin Huber, who was placed on injured reserve Tuesday after breaking his jaw on a violent blindside block from Pittsburgh's Terence Garvin, was officially listed on the injury report as out for this week's game.
