Concussion has Bengals' Harrison inactive

CINCINNATI -- A concussion will have Cincinnati Bengals linebacker James Harrison sidelined for Sunday afternoon's game at Paul Brown Stadium.

The veteran was among the seven inactive players the Bengals announced before the important non-conference contest against the Minnesota Vikings. Bengals cornerback Terence Newman, who missed last week's game at Pittsburgh, also was declared inactive as he tries to come back from a knee injury suffered in Cincinnati's last home game two weeks ago.

Harrison's concussion came in the first quarter of his homecoming game at Pittsburgh. In his first game back at Heinz Field since signing with the Bengals this offseason, the former longtime Steeler didn't play for long. His injury preceded another ugly one to punter Kevin Huber, who was lost for the season after being blindsided by Steelers return-team player Terence Garvin. Defensive end Carlos Dunlap also was among those who entered this past week's practices with lingering effects from an injury picked up last Sunday night. He was concussed at the end of the game.

Unlike Harrison, though, Dunlap was able to clear the protocol for his concussion. He was designated as active. Offensive tackle Andrew Whitworth, who also suffered his own concussion during a practice this past week, cleared concussion protocol, too. He will be starting at left guard, just like he has the previous two games.

One other inactive of note: defensive tackle Devon Still. A back injury this week had Still limited in practices and forced him into being declared questionable.

Michael Boley will take Harrison's spot when the Bengals go into packages that feature that particular linebacker position. Kirkpatrick will make his second straight start at cornerback in place of Newman.

Along with Whitworth's inclusion at left guard, the Bengals also will keep Mike Pollak at right guard, even though Kevin Zeitler is active. Before a foot injury at Baltimore last month, Zeitler had been the team's starter at the position. Even though he has now been active the past three weeks, Zeitler hasn't yet relieved his former backup Pollak.

Here's the full list of Bengals and Vikings inactives:

Bengals: WR Dane Sanzenbacher, CB Terence Newman, WR Ryan Whalen, LB James Harrison, RB Rex Burkhead, OT Dennis Roland, DT Devon Still

Vikings: QB Josh Freeman, CB Xavier Rhodes, RB Matt Asiata, OT Mike Remmers, WR Rodney Smith, DT Chase Baker, DE Justin Trattou
