Carlos Dunlap suffered a fourth quarter concussion against the Steelers

Initial reports from Wednesday's practice was that defensive end Carlos Dunlap was one of three players sitting, joined by linebacker James Harrison (concussion) and Terence Newman (knee). When the team released the injury report, Dunlap's issue was listed as a concussion.

The injury occurred on the final play of the game when his head hit on Steelers tight end Matt Spaeth's knee just prior to the players shaking hands and departing the field.

This is Dunlap's second concussion; the first wiping out nearly his entire preseason earlier this year and places Cincinnati's already questionable pass rush into further jeopardy. Currently undergoing concussion protocols, if Dunlap is unable to practice on Thursday, his chances to play against the Minnesota Vikings will appear slim.

James Harrison, who missed practice on Wednesday, is also undergoing concussion protocols after a first quarter exist with concussion-like symptoms. George Iloka also suffered a head injury against the Indianapolis Colts and was believed to have suffered a concussion, however he passed all tests and practiced that Wednesday.
